See the Connecting Your Trailer section for trailer hook up instructions. A U-Haul representative can assist if you require assistance.

Important Trailer Towing Information

  • Prevent WHIPPING by properly loading the trailer. Load 60% of the cargo weight in the front half of the trailer box. Loading heavier in the rear will cause the tow vehicle and trailer “combination” to begin WHIPPING, which is violent and uncontrollable sway.
  • SIDE to SIDE MOTION (SWAY) THAT BEGINS as you reach a certain speed, will likely become WHIPPING at higher speeds. If you notice sway beginning SLOW DOWN IMMEDIATELY by letting off the gas pedal. Then stop to reload the trailer heavier in the front as soon as possible.
  • IF WHIPPING or SWAY OCCURS, DO NOT steer, DO NOT apply your brakes, and NEVER speed up. Let off the gas pedal and hold the steering wheel in a straight-ahead position.
  • A "combination disturbance" is improper handling, whipping, sway, over-steering or other deviation of the tow vehicle or trailer from their intended path, due to one or more causes (improper loading, steering inputs, excessive speed, crosswinds, passing vehicles, rough roads, etc.). IF A COMBINATION DISTURBANCE OCCURS, DO NOT steer or brake. Steering or braking during a disturbance can cause a loss of control or crash.
  • If a WHEEL GOES off the paved roadway, DO NOT steer sharply and DO NOT brake. Let off the gas pedal and slow down below 25 mph. Then steer gradually back onto the roadway. Proceed with caution entering traffic.

The trailer may be wider than the tow vehicle. Allow for this by driving in the center of your lane.

If release-lever is NOT fully down (D-Figure 3), drive forward slightly, or push rearward on the trailer, until the release-lever moves to fully down position.

Things to Remember

  • Do not allow yourself to become distracted.
  • Ensure that the coupler is properly fastened to the hitch-ball before moving to the next step.
  • Check all connections at each stop.
  • Make sure the hitch and hitch-ball are securely attached to your tow vehicle and that the trailer coupler is properly connected to the hitch-ball.
  • Use the checklist at the end of these instructions.
  • If you suspect or detect that something is wrong, contact the nearest U-Haul representative.

Safety Cables

The purpose of the safety cables is to keep the trailer connected to your tow vehicle in the unlikely event the ball comes off the hitch or the coupler comes off the ball. Safety cables are attached to the trailer tongue and are equipped with “S”-hooks on their free ends. DO NOT tow the trailer without the safety cables securely attached to the towing vehicle.

DO NOT attempt to pull the trailer by the safety cables alone, unless this is necessary to get the combination off the roadway to a safe place.

NOTE: This trailer was originally equipped with safety cables, but may have one or more safety chains if a repair was needed. If any safety chains are present, follow these same instructions as safety cables, with exceptions only where safety chains are specifically listed.

A detailed illustration of a trailer attached to a trailer hitch with wiring connections and back-up safety chains.
Figure 4

The right cable (A) crosses underneath the trailer tongue (B) and hooks to the left side of the tow vehicle permanent hitch (C), "D"-rings, frame or structure, or to the tow vehicle bumper brackets. (Figure 4) Do not attach cables to the ball or to a ball mount that is removable. The left cable hooks to the right side in the same manner. Crossing the cables under the tongue allows the minimum amount of slack for turning. The "S"-hooks (D) on safety CABLES should be hooked to attachment holes on the hitch, if present. For safety CHAINS the "S"-hooks can be hooked to the attachment holes or passed through these holes and hooked back to a link in the chain. Control safety CHAIN slack by hooking the chain back to itself or by twisting the links to shorten chain. Be sure the "S"-hooks have a functional spring clip retainer (E), or are secured with a rubber retainer. The cables need slack to allow your vehicle to make turns. Make sure these cables attach securely to your tow vehicle and do not drag on the roadway.

A detailed illustration of a trailer attached to a trailer hitch showing the emergency brake wiring connection.
Figure 5

Emergency Brake Cable

Trailers with brakes have a third cable, called the emergency brake cable (F). (Figures 4 and 5) This cable applies the brakes automatically in the unlikely event of a separation of the trailer from the tow vehicle. Attach this cable as close to the vehicle center as possible; to the tow vehicle permanent hitch, (C) "D"-rings, frame or structure, or to the bumper brackets. The "S"-hook (G) on this cable should be hooked to an attachment hole on the hitch, if present. Be sure the "S"-hook has a functional spring clip retainer, or is secured with a rubber retainer. Some slack is necessary to prevent the emergency brake from activating on turns or inclined driveways.

Do Not Tow with the Emergency Brake Engaged

NEVER tow the trailer unless the emergency brake pedal (H) is in the fully rearward position. (Figure 5) See decals also, for proper position of emergency brake pedal for towing. The emergency brake cable (F) attaches to the emergency brake pedal (H) on top of the hydraulic brake mechanism. When the emergency brake cable is pulled forcefully, the emergency brake pedal will move forward and lock, activating the trailer brakes. The trailer brakes will remain activated until the emergency brake pedal is reset to the fully rearward position. Call U-Haul at 1-800-528-0355 if you need the emergency brake reset.

Lighting Connections

Make sure all tow vehicle and trailer lights function properly. The connecting wires need slack to allow your tow vehicle to make turns. Do not allow wires to drag on the roadway.

4-Way Flat

If your tow vehicle has a 4-way flat lighting system, connect the trailer lights by plugging into the tow vehicle connection plug. If your tow vehicle does not have a 4-way flat lighting connection system, your U-Haul representative will be able to instruct you on the connection steps and products available for your vehicle.

Disconnecting Your Trailer

Follow the instructions in this section while unhooking the U-Haul trailer. A U-Haul representative can assist you if you require assistance.

Park the trailer on level ground in a straight line with the tow vehicle, in park, motor off, and parking brake set. Disconnect trailer lighting wiring harness from the tow vehicle by unplugging at the vehicle connector. Unhook both safety cables and the emergency brake cable from the hitch.

Drop & Tow Automatic Coupler

Figure 6

Raise the coupler release-lever (G) to a vertical position. (Figure 6) If release-lever will not raise with normal hand effort; push rearward on the trailer, or drive forward slightly, until release-lever will raise by normal effort. Next, lift the coupler completely off the hitch-ball with the tongue jack, then carefully lower the trailer tongue to the ground. Lower the release-lever to fully down position when finished. (See Figure 1).

Loading Your Trailer

  • Failure to follow these loading instructions may result in sway or WHIPPING and lead to total loss of control.
  • NEVER exceed the trailer’s maximum gross weight, which is posted inside the trailer. NEVER exceed a lower allowed gross weight and “allowed cargo weight” as listed on your rental contract.
  • NEVER load cargo on the outside of the trailer or extend cargo out the rear of the trailer. Secure all cargo inside trailer. Unsecured cargo may (1) shift and cause dangerous WHIPPING or (2) be ejected and cause a roadway hazard.
  • Make sure the trailer is securely attached to the tow vehicle during loading and unloading.

Loading Cargo / Equipment

An illustration of the proper weight distribution when loading a trailer
Figure 7

Load heavier in the front half of the trailer (60% of the cargo weight). Secure your cargo or equipment using the D-ring tie-downs on the trailer or the top rail and rail supports. Cargo or equipment not properly secured may shift, be damaged or be ejected under normal driving conditions.

Secure your load, it’s the law. A U-Haul representative can advise you on the products available to secure and protect your goods.

Loading Vehicle-In-Tow

Loading and securing the vehicle-in-tow onto the trailer is the customer’s responsibility. When loading or unloading the vehicle-in-tow, have someone guide you from a safe distance.

For a video of loading a trailer go to: youtube.com/uhaulofficialvideos

  • The vehicle-in-tow MUST be loaded facing forward (front wheels closest to hitch). Failure to load facing forward may result in sway or WHIPPING and lead to total loss of control.
  • DO NOT load cargo in your vehicle-in-tow. Loading cargo in your vehicle-in-tow may result in sway or WHIPPING.
  • The trailer may be used to carry certain large items when a vehicle-in-tow is NOT installed. U-Haul will validate your intended use and provide special instructions if you intend to do this. Be sure to load trailer heavier in front and to secure the load.
  • Before loading your vehicle-in-tow, make sure the trailer is securely attached to your tow vehicle hitch. Check that the coupler connection is secured, and release-lever is fully down. Make sure the safety cables are properly connected. During the loading process, keep children and others at least 25 feet away.

Complete each step below, in sequence.

  1. Park the properly hitched trailer on level ground in a straight line with the tow vehicle; in park, motor off, and parking brake set.
  2. Pull both ramps (figure 8) completely out and lower to the ground for loading.
  3. Position the vehicle-in-tow behind the trailer, FACING FORWARD, and centered as well as possible. Make sure that the front tires will be on the ramps BEFORE driving on the ramps.
  4. Approach ramps slowly. Make sure there is enough clearance for spoilers, air dams, etc. If more clearance is needed, lift the front of the trailer using the tongue jack. DO NOT unhook the trailer from the tow vehicle if the tongue jack is needed. The spoiler or air dam may also be removed to allow clearance. Do not load if there is not enough clearance for these items.
  5. Keep doors closed and drive slowly up the ramp and forward on the platform until the rear tires are centered on the decal (Figure 8) or the front tires are resting firmly against the wheel stops. DO NOT brake quickly or ram the tire stops at the front of the platform. Shift to park and set PARKING BRAKE. Vehicle-in-tow tires must be turned straight ahead and fit on trailer platform without overhanging sides.
  6. Exit the vehicle-in-tow. Carefully step off the trailer, using the step provided if necessary.
  7. Lift and push both loading ramps back into the storage compartments, inward until the ramp latch fully engages.

Securing the Vehicle-In-Tow

  1. Secure vehicle in tow with four 3,300 lb. (or higher) rated cam-buckle or ratchet-type tie-down straps. (Two for front and two for rear) attach tie-down straps from each front corner of vehicle frame to lower front D-rings located inside trailer. (refer to your vehicle owner’s manual for other recommended attachment points) tighten straps evenly. Attach tie-down straps from each rear corner of vehicle frame to rear D-rings located inside trailer. Tighten straps to prevent vehicle rear from moving. Make sure all straps are tight and avoid contact with hot components such as exhaust pipes.
  2. Connect the two (2) vehicle security chains, found on the front and rear trailer cross-members, to the vehicle-in-tow lower control arm, frame, or other structural member. Keep the security chains away from brake and fuel lines and other items that may be damaged by the chain. DO NOT place the chain hook on the vehicle frame member or other structural member. Loop the chain around the member and place the "S"–hook through the hole in one of the chain links. Leave about two inches of slack in the security chain and be sure the "S"–hook is secured with a rubber retainer. DO NOT tow without vehicle-in-tow properly secured.

    Failure to properly install security chains and tire straps may result in the vehicle-in-tow separating from the trailer. This may result in a combination disturbance, a vehicle crash, or damage to your vehicle-in-tow.

  3. If the tongue jack was used to add clearance for loading, make sure the jack is fully raised off the ground before towing the trailer.

    Failure to fully raise the tongue jack off the ground before towing can cause the trailer to become detached from the tow vehicle or cause a combination disturbance.

Motorcycle Loading and Securing

Walk or ride your motorcycle (MC) up the ramp. Always load a MC facing forward. Secure the MC with four 1,200 lb. rated cam-buckle or ratchet-type tie-down straps. (Two for MC front and two for rear) Attach tie-down straps from each side of handlebars or shock towers to lower front D-rings located inside trailer. (Refer to your MC owner’s manual for other recommended attachment points) Tighten straps evenly, compressing shocks about halfway to ensure that MC is firmly secured and cannot move side to side. Attach tie-down straps from each side of rear MC frame or wheel to lower center or rear D-rings located inside trailer. Tighten straps to prevent MC rear from moving. Make sure all straps are tight and avoid contact with hot exhaust pipes. If cargo is loaded with a MC, also follow instructions above for loading the trailer.

Check Tire Straps and Connections

When loading and securing the vehicle-in-tow is complete, take a test drive around the block, including slow left and right turns. Then recheck the straps and re-tighten as needed.
Recheck the straps and all hookup connections after the first 5 miles, again after 50 miles, and thereafter at every stop.

NEVER tow without properly installed straps and vehicle-in-tow security chains.

Tongue Weight

This guideline is to help you make sure the trailer is loaded properly by checking the tongue weight. DO NOT disconnect the trailer to do the following.

  1. Step 1: With the tow vehicle and trailer empty, and the trailer attached to your tow vehicle, measure the distance from the ground to the top of the trailer coupler release-lever.
  2. Step 2: With the trailer fully loaded and the tow vehicle empty, measure the distance from the ground to the top of the trailer coupler release-lever.
  3. Step 3: Subtract the answer in Step 2 from the answer in Step 1. (Answer 1 – Answer 2).
A illustration of a trailer tongue and a ruler, showing the correct measurement range of where the trailer tongue should be when attached to the towing vehicle.
Figure 9

If your answer in Step 3 is greater than or equal to 1 inch, your trailer has enough tongue weight. If your answer is less than 1 inch, it is recommended that you reload your trailer and put more weight in the front of the trailer. An answer less than 1-inch can cause sway or WHIPPING.

Take your combination for a short test-drive. If you feel the combination is not handling properly, reload your trailer. If you are not sure the trailer is properly loaded, get help at uhaul.com/help or call Roadside Assistance at 1-800-528-0355 or take your combination to the nearest U-Haul location and ask if your trailer is properly loaded.

Do Not Overload!

U-Haul trailers are designed to move household-type goods. Commercial loads (such as wood, food products, machinery, etc.) are heavier than household goods. DO NOT load the trailer more than one-third full if you intend to move these items. Sand, dirt and gravel are even heavier and require that you DO NOT load more than a maximum of four inches above the trailer floor.

Every U-Haul trailer has an empty and maximum gross (fully loaded) weight labeled on the inside of the trailer at the front. Never load the trailer so that it exceeds this maximum gross weight. Your rental contract may list a lower ALLOWED cargo weight, based on your specific tow vehicle, never exceed these weights. If in doubt, check the weight at a commercial or state scale. (Search Internet or Yellow Pages under "Public Scales.")

Hazardous Materials

  • DO NOT transport hazardous materials, corrosives, explosives or flammables such as gasoline or paint thinner. A container that is almost empty is just as dangerous as a full one. Flammables may explode or ignite through spontaneous combustion from vehicle movement.
  • Empty and air out the tanks on lawn mowers, camping stoves and lanterns before loading.
  • NEVER fill a portable fuel container IN or ON the trailer. Set tanks on the ground to fill to avoid static electricity and prevent sparks.

Securely close and properly package household cleaning products.

Loading Your Combination

  • NEVER exceed the trailer’s maximum gross weight, which is posted inside the trailer. Never exceed a lower allowed gross weight and allowed cargo weight as listed on your rental contract.
  • NEVER overload your tow vehicle. Do not exceed the gross vehicle weight rating (GVWR) and the gross axle weight ratings (GAWR), which are posted on a label inside the driver’s door opening.
  • NEVER load cargo on the outside of the trailer or extend cargo out the rear of the trailer. Secure all cargo inside trailer. Unsecured cargo may (1) shift and cause dangerous WHIPPING or (2) be ejected and cause a roadway hazard.
  • DO NOT transport or store hazardous materials, corrosives, explosives or flammables.

Equipment

Your Tow Vehicle

For occasional towing, your vehicle, when properly equipped, can tow any recommended U-Haul trailer, if the loaded weight of the trailer does not exceed your vehicle’s curb (empty) weight. Your vehicle can also tow any U-Haul trailer equipped with brakes, provided the curb weight of your tow vehicle is at least 80% of the loaded weight of the braked trailer.

DO NOT use a tow vehicle different than listed on your rental contract, unless U-Haul validates the new vehicle for you.

Changes made to your tow vehicle after it was manufactured can affect its ability to tow. These changes can include different tires, suspension changes, etc. Check your owner’s manual or with an authorized automotive dealer to make sure any changes to your tow vehicle are approved.

DO NOT tow the trailer if your tow vehicle has changes that are not approved.

DO NOT drive on a compact spare tire any further or faster than specified by your vehicle manufacturer’s instructions.

Tow Vehicle Maintenance

Maintenance and condition of your tow vehicle’s engine, transmission, steering, suspension, front-end alignment and tires may affect your vehicle’s ability to tow the trailer. Have an authorized repair facility inspect and repair your vehicle BEFORE towing.

To find the towing capabilities of the engine, transmission and axles of your vehicle, refer to the owner’s manual, or check with an authorized dealer.

Towing Equipment Requirements

Hitches

Hitches must be able to tow the weight of the trailer and its cargo. A U-Haul representative can advise you on the available hitches and components that meet the requirements for your intended use.

Hitch Balls

Hitch-ball size of 2 inches is proper for a U-Haul coupler. A U-Haul representative can advise you on the correct ball size and weight rating for the trailer.

Other Hitch Systems

Weight distribution hitches or sway control devices ARE NOT USED for towing a U-Haul trailer. Towing a properly loaded trailer does not require these devices. These devices may have a negative effect on vehicle handling and braking and may restrict the operation of the trailer coupler mechanism.

Lights and Mirrors

When towing a trailer, all lights must be operational. Your tow vehicle may require external mirrors on both sides. A U-Haul representative can advise you of the systems available if your vehicle is not properly equipped.

Loading Your Tow Vehicle

NEVER overload your tow vehicle. Do not exceed the gross vehicle weight rating (GVWR) and the gross axle weight ratings (GAWR), which are posted on a label inside the driver's door opening.

To find how much weight you are allowed to put in your tow vehicle:

  1. Step 1: Find your tow vehicle’s GVWR on the label inside the driver’s door.
  2. Step 2: Subtract the curb (empty) weight of your tow vehicle from the GVWR. Contact a U-Haul representative for help in finding the curb weight of your tow vehicle.
  3. Step 3: Subtract 400 pounds from the answer in Step 2 if your trailer has 4 tires. This accounts for trailer tongue weight.

The answer in Step 3 is the amount of weight you can put in your tow vehicle. This weight includes driver, passengers, cargo and any additional equipment. If the rear of your tow vehicle seems low, reduce the load in the rear seat, trunk or cargo bed areas. Too much load in the rear can affect handling.

Tire Pressure

Set all tires to the proper pressure. Find the recommended COLD pressure on the tire sidewall, owner’s manual, your vehicle’s door decal or on the trailer decal. DO NOT put more pressure in the tire than is indicated on the tire sidewall. Tire pressures go up during driving. DO NOT let off this extra pressure.

Air pressure in the rear tires of some tow vehicles may be increased to accommodate the additional weight of the trailer. Inflate rear tires approximately 6 psi above normal, but do not exceed the pressure limit stamped on tire.

Your Vehicle-In-Tow

  • The MAXIMUM weight the vehicle-in-tow can be is determined by your specific tow vehicle and hitch components and which model TH you rented. This is done during the rental process, so DO NOT place a vehicle-in-tow on the TH that is different than listed on your rental contract. If you need to change your tow vehicle or vehicle-in-tow; contact U-Haul to validate the new vehicle(s) and update your contract. Exceeding these limits may cause a disturbance or damage to your tow vehicle, TH or vehicle-in-tow.
  • The vehicle-in-tow tires MUST fit on the TH platform and ramps without hanging excessively over the sides, and fit within the TH fenders. Tires on some narrow track width vehicles may extend past the inside edge of the ramps, be sure the vehicle is centered carefully to stay on the ramps and platform.
  • Low hanging equipment on your vehicle-in-tow, such as spoilers, air dams, ground effects, etc., may be damaged by contact with the TH during loading and unloading. It is the customer’s responsibility to make sure there is enough clearance for these items. If there is not enough clearance for these items, they must be removed; or follow simple steps to reduce the ramp angle – such as shimming with lumber or loading from a curb. For tips on how to reduce the ramp angle go to: youtube.com/uhaulofficialvideos
  • The TH is designed for carrying vehicles with standard height, factory-installed suspensions. Modified, lowered or sagging suspension vehicles may not fit on the TH, damage may occur to the vehicle during loading or transport. The customer is responsible for damage to vehicles with low suspensions.

Towing

Slow Down When Towing

  • AVOID CRASHES by slowing down. Reduce your speed from what you would normally drive without a trailer under similar road conditions. The maximum recommended speed is 55 mph when towing a U-Haul trailer. Do not exceed any posted speed limit.
  • DRIVE DEFENSIVELY–anticipate stops, brake early, and never follow closely.
  • BEFORE GOING DOWNHILL, slow down and shift the transmission into a lower gear. DO NOT RIDE BRAKES on downgrades.
  • WHEN GOING UPHILL, use lower gears and plan on slowing down. Stay in the slow lane. Turn flashers on if speed drops below 45 mph. Watch your gauges and pull off the roadway if the engine temperature gets too high.
  • Pull off the road BEFORE your engine gets too hot. If the engine gets too hot it will shut off by itself (stall) and may leave you stranded in traffic or damage your vehicle.
  • Slow down for curves, adverse weather, hazardous road conditions, road construction and expressway exits. Do not feel secure because the trailer tows easily at higher speeds. A road hazard that could be avoided at 55 mph, may become unavoidable at a higher speed.
  • When driving at a lower speed you are less likely to lose control of any vehicle, than when driving at a higher speed. Excessive speed is a major cause of accidents.
  • U-Haul does not recommend using cruise control or overdrive when towing a trailer.

Before Towing and on the Road

  • Use the checklist at the end of these instructions before towing and while on the road.
  • Make sure your tow vehicle is properly equipped and maintained. Be sure all tires are inflated properly.
  • ALWAYS wear your seat belt. Be sure children are properly restrained.
  • DO NOT drive when you are fatigued, sleepy or distracted. Avoid driving at night.
  • NEVER TEXT while driving. NEVER be distracted by using a cell phone while driving. Distracted driving is a major cause of crashes. If you need to text or use a cell phone, find a safe place to exit the roadway.
  • NEVER drive under the influence of alcohol or any substance that might impair your vision, judgment or ability to control the vehicle.
  • NEVER allow passengers to ride inside or on the trailer. Passengers risk injury due to shifting cargo, asphyxiation and lack of collision protection.
  • No open or soft-top sport utility vehicle is allowed to tow a U-Haul trailer, because in the event of a crash, these vehicles offer less collision and ejection protection.

Stopping and Following Distance

Your combination is heavier and longer than your vehicle alone. This means it will take you longer to stop.

  • Allow at least 4 seconds between you and the vehicle in front of you. Start counting when the back of the vehicle in front of you passes a fixed object, such as a line or crack on the road. If the front of your vehicle reaches the object before the end of the 4 seconds, increase your distance.
  • If you are driving in adverse weather, such as rain, snow, or fog, use at least a 5 second gap.

Whipping

A illustration of a vehicle towing a trailer leaving S-shaped skid marks on a road.
Figure 10

Whipping is violent and uncontrollable sway caused by loading a trailer heavier in the rear half. Persistent side to side sway motion is not normal. If this occurs at a certain speed, it is a signal that WHIPPING will likely occur if speed is increased by a small amount. If you notice this behavior immediately slow down and maintain at least 10 mph below the speed this sway was first noticed. Then stop at the first opportunity and reload the trailer heavier in the front half to correct this problem. See next section.

Combination Disturbances

A "combination disturbance" is improper handling, whipping, sway, over-steering or other deviation of the tow vehicle or trailer from their intended path, due to one or more causes (improper loading, steering inputs, excessive speed, cross winds, passing vehicles, rough roads, etc.).

If whipping or other combination disturbance occurs:

  • Let off the gas pedal. NEVER speed up to try to control a combination disturbance.
  • DO NOT apply your brakes.
  • HOLD THE STEERING WHEEL in a straight-ahead position. DO NOT try to control the combination disturbance by turning the steering wheel.

After whipping or other combination disturbance has stopped:

  • Pull a safe distance off the roadway and stop. Get all occupants out of the vehicle and away from the roadway.
  • Check the cargo in the trailer to make sure the load has not shifted. Make sure the trailer is loaded heavier in front.
  • Check that all tires are properly inflated and that all lug nuts are tight.
  • Check the trunk or rear cargo area of the towing vehicle to make sure it is not overloaded.
  • REDUCE SPEED to 55 mph or LESS. Combination disturbances happen most often at higher speeds.

If the combination disturbance persists after correcting any items above, contact the nearest U-Haul representative and have them inspect or exchange the trailer. If the combination disturbance still occurs, something is wrong with your tow vehicle. DO NOT continue towing the trailer, contact U-Haul for an alternative solution.

Passing

  • Your combination is heavier and longer than your tow vehicle alone and will require more time and distance to pass.
  • Passing by another vehicle in the same or opposite direction can result in a combination disturbance. See the Combination Disturbances Section for what to do if this happens.

Hills

  • SLOW DOWN BEFORE starting downhill. Shift into lower gear and let off the gas pedal, this allows the engine to help you control your speed. Combination disturbances happen more frequently going downhill and at higher speeds.
  • DO NOT ride the brake pedal going downhill. Prolonged use of your brakes results in overheating and possible loss of braking. When you need to slow down, apply the brake pedal and slow down below the intended speed. Then let off the brake pedal completely. Repeat as needed.
  • Shift into lower gear to prevent your tow vehicle from jerking due to engine lugging when traveling up hills. This will improve gas mileage and reduce engine overheating.
  • When traveling up long or steep grades, shift to a lower gear and expect that your vehicle may slow down significantly. Stay in the lane designated for slower traffic. Turn on flashers if speed drops below 45 mph and other traffic is traveling faster than you. Watch gauges and if temperature is climbing turn off A/C and slow down until the temperature stabilizes well below "hot". This may be at 45 mph or less. If the temperature is getting too high pull off to a safe place and stop. After stopping do not turn the engine off, shift to park / neutral and let it cool down at idle; or to cool faster increase engine rpm slightly.

Road Shoulders

If a wheel goes off the paved roadway:

  • DO NOT turn the steering wheel sharply.
  • DO NOT apply your brakes.
  • Let off the gas pedal and slow down below 25 mph. Then steer gradually back on the roadway. Proceed with caution entering traffic.
    Sometimes the trailer is wider than the tow vehicle. Allow for this by driving in the center of your lane.

Backing Up

Keep your hand at the bottom of the steering wheel. To move the trailer left, move your hand left. To move the trailer right, move your hand right. If your combination starts to jackknife, or isn’t headed where you want it, STOP. Pull forward to straighten out, then start again.

  • Get help to watch as you are backing. If you cannot get help, exit your vehicle and make sure there are no people or obstructions in the way.

Turning and Sharp Corners

Avoid U-turns or turning too sharp on street corners, in gas stations or parking lots. Because the combination is longer the trailer will track inside the turn and may sideswipe a vehicle or object. Drive slightly past the corner before turning or turn wider than you would with a car to avoid this. Or simply plan ahead and avoid sharp turns where you can.

Unloading Vehicle-In-Tow

  • Before unloading, make sure TH is securely attached to the tow vehicle hitch. Check that the coupler connection is secured, and the release-lever is fully down or hand-tight. Make sure the safety chains are properly connected. Place the combination on level ground. Make sure the TH is directly behind the tow vehicle, in a straight line. Set the tow vehicle’s PARKING BRAKE firmly and turn the motor off. Allow room behind the TH to back the vehicle-in-tow clear of the TH.
  • During the unloading process, keep children and others at least 25 feet away.

Complete each step below, in sequence.

  1. Disconnect the straps and lay them to the sides of the TH.
  2. Disconnect the security chains from the vehicle in-tow and lay them aside.
  3. Pull both loading ramps completely out and lower to the ground.
  4. If more clearance or better ramp angle for the vehicle-in-tow was needed during the loading process, lift the front of the TH using the tongue jack. DO NOT unhook the TH coupler from the tow vehicle hitch if using the tongue jack to create better loading clearance.
  5. Enter the vehicle-in-tow and release the parking brake. Leave all doors CLOSED during the unloading process.
  6. Straighten the front wheels of the vehicle-in-tow if necessary, then SLOWLY back the vehicle-in tow off the TH.
  7. Lift and push the loading ramps back into the storage compartments, push inward until the latch engages the ramp. NEVER tow the TH with the loading ramps out.
  8. If the tongue jack was used to add clearance, make sure the jack is fully raised off the ground before towing the TH.
  9. Stow the security chains.

Breakdowns

Immediately park your combination in a safe place, completely off the roadway. Turn on your emergency flashers. Get all occupants out of the vehicle and away from the roadway.

If you must continue on the roadway to reach a safe place off the road, turn on your emergency flashers and proceed with caution.
