A U-Haul car towing trailer can make a move or vehicle transfer easier, but a reservation alone doesn’t confirm that your combination is safe. Before booking, verify three things: the tow vehicle can handle the fully loaded trailer, the car is approved for the selected equipment, and the hitch and wiring match U-Haul’s requirements. Start with the exact year, make, model and trim of both vehicles, then compare the rental guidance with the tow vehicle’s owner’s manual. If any detail is uncertain, resolve it before pickup; discovering a mismatch at the rental counter can mean delays, extra costs or a trip you can’t make as planned.

Which U-Haul car towing trailer should you choose?

U-Haul offers two different types of equipment for transporting a car: the Auto Transport and the Tow Dolly. They don’t support a vehicle in the same way, so choosing between them depends on the car’s specifications and towing instructions—not simply on which trailer is available.

Equipment How it carries the car May suit Key limitation
U-Haul Auto Transport All four wheels are carried on the trailer. Cars that are approved for the Auto Transport and fit its requirements. The tow vehicle must handle the combined load, and the car must meet the trailer’s fit and loading requirements.
U-Haul Tow Dolly The front wheels are carried on the dolly while the rear wheels remain on the road. Some vehicles whose manufacturer and U-Haul requirements permit this towing arrangement. Drivetrain, transmission and vehicle-specific towing restrictions can rule it out.

The Auto Transport keeps all four tires off the road, but that doesn’t automatically make it suitable for every car or tow vehicle. A Tow Dolly can be a practical option when the car’s manual allows the wheels left on the road to roll and U-Haul confirms the pairing. If the car is all-wheel drive, electric, hybrid or has special transmission requirements, check its owner’s manual before considering a dolly. Do not assume that a general rule for one drivetrain applies to every model.

Use U-Haul’s equipment compatibility prompts with the exact vehicle details, and ask the rental location to resolve any uncertainty before booking. An answer that covers a model family may not account for a particular trim, drivetrain or factory towing package.

Check the tow vehicle’s capacity—not just its advertised tow rating

The tow vehicle must be able to pull the trailer with the car loaded. The relevant figure is not the car’s weight alone, nor the empty trailer weight. Use the loaded combination and the limits that apply to your specific tow vehicle, hitch and trailer.

Start with the owner’s manual and the vehicle manufacturer’s towing information for your exact configuration. Tow ratings can vary with engine, drivetrain, model year and factory equipment. Check the vehicle’s maximum trailer weight as well as its gross combined weight rating (GCWR), gross vehicle weight rating (GVWR), axle ratings and payload limit. The hitch and receiver have their own limits, which also have to be respected.

Remember that passengers and cargo in the tow vehicle count toward its weight limits. The trailer’s tongue weight also loads the tow vehicle and hitch, so it matters even when the trailer’s total weight appears to be within the tow rating. If the car being transported has heavy items inside, remove them where possible and include any remaining load in your calculations.

  • Find the relevant manufacturer limits. Use the owner’s manual, towing guide and vehicle labels for the exact tow vehicle.
  • Identify the loaded trailer weight. Account for the trailer, the car and any permitted cargo—not just the empty trailer.
  • Check the hitch separately. The receiver, ball mount and ball must meet the requirements for the selected trailer and load.
  • Allow for people and luggage. Their weight affects the tow vehicle’s payload and may affect other limits.

Don’t treat U-Haul’s confirmation as permission to exceed a manufacturer rating. If the figures are unclear or the combination is close to a limit, ask the vehicle manufacturer or a qualified towing professional to help interpret them. If the combination doesn’t comply, use a properly rated tow vehicle or consider professional vehicle transport instead.

Confirm the car fits the trailer and can be towed that way

Give U-Haul the transported car’s exact year, make, model and trim. A model name by itself may not be enough: versions can differ in weight, dimensions, drivetrain or ground clearance. The compatibility check should account for the specific car and the particular U-Haul equipment you intend to rent.

For a Tow Dolly, the central issue is whether the car can safely be towed with its rear wheels on the road. Read the car’s owner’s manual for towing instructions, including any restrictions related to transmission, drivetrain, speed or distance. Some cars require a different method of transport. If the manual prohibits the dolly arrangement or is unclear, don’t rely on guesswork; ask the manufacturer or choose equipment that keeps all four wheels off the road if that option is approved for the car.

Also ask about practical loading requirements. Check whether the car needs to run, steer, roll or have particular tire and clearance conditions to load the selected trailer. If it is damaged or inoperable, describe its condition before reserving. A suitable trailer on paper may still be difficult or impossible to load safely if the car cannot be positioned as required.

For vehicles with low ground clearance, modified suspension, wide tires or other non-standard dimensions, confirm fit before travelling to the pickup location. Do not assume that a car will fit because a similar vehicle has been transported on the same equipment.

Check the hitch, electrical connection and braking requirements

A receiver hitch is only one part of the setup. The hitch, receiver, ball mount and trailer coupler must be compatible with each other and rated for the load. Confirm the required ball size and any equipment specifications with U-Haul rather than relying on the ball that happens to be installed. The hitch’s label or documentation can help identify its rating, but it does not establish that the tow vehicle itself can handle the trailer.

The trailer’s lights must connect to the tow vehicle and work correctly. Check that the wiring connector matches, and confirm that turn signals, brake lights and running lights function after hookup. Find out what braking system the selected trailer uses and whether the tow vehicle or local rules require additional equipment. Don’t assume a brake controller is either required or unnecessary without checking the trailer details and applicable requirements.

Before booking, make sure your planned setup includes the equipment U-Haul requires. If a hitch, ball mount, wiring adapter or other component is missing, ask about it in advance. Sorting out the mismatch at pickup can delay the rental and may leave you unable to tow safely.

A booking and pickup process that catches problems early

  1. Collect exact vehicle details. Record the year, make, model and trim of the tow vehicle and the car being transported. Include drivetrain and any relevant modifications.
  2. Check the car’s towing instructions. Read its owner’s manual, especially if you’re considering the Tow Dolly or the car has a specialised drivetrain.
  3. Verify tow ratings and hitch limits. Compare the loaded combination with the limits for the tow vehicle, hitch, receiver, ball mount and trailer.
  4. Run U-Haul’s compatibility check. Confirm that the chosen equipment is suitable for both vehicles. Raise uncertain details with the rental location before reserving.
  5. Review the complete rental quote. Ask what the quote includes and how mileage, rental duration, one-way arrangements, taxes, equipment and protection options are handled for your booking.
  6. Inspect before leaving. Check the trailer’s tires, lights, coupler and visible components. Ask the rental staff to address damage or missing equipment, and follow the supplied instructions for hookup and loading.
  7. Recheck the connection and load. Use U-Haul’s instructions for coupling, safety chains, loading and securing the car. Test the lights and check that straps and other restraints are fitted as directed before travelling.

Photograph existing damage to the rental equipment and the transported car before departure. Keep the rental agreement and any instructions with you. If the car is being transported because of a breakdown or damage, confirm how the rental terms apply to its condition and loading needs before you arrive.

Budget for more than the trailer rental

The cost depends on the equipment, rental dates and locations, route, duration and other terms of the booking. Get a quote for the actual trip rather than using a price from a different location or rental arrangement. Ask whether the estimate includes all required towing equipment and clarify how extra time, mileage or a change in the return plan would be charged.

Insurance deserves a separate check. Don’t assume your personal auto policy or credit card covers the rental trailer, damage to the car being transported, or every possible loss. Ask your insurer what the policy covers while the car is being towed, then read the U-Haul agreement and any protection option terms before deciding. Coverage can depend on the policy and the circumstances of a claim.

If a compatible tow vehicle or suitable hitch would require substantial expense, compare the full cost with hiring a vehicle-transport service. That alternative may make more sense when the car cannot be towed on a dolly, the tow vehicle is under-rated, or the route and equipment setup are beyond your experience. Include loading, insurance and timing in the comparison, not just the headline rental charge.

Drive with the loaded trailer in mind

A car and trailer change the length, weight and handling of the tow vehicle. Allow more room for turns and stopping, avoid abrupt steering or braking, and follow the speed guidance and operating instructions for the tow vehicle and rental equipment. Choose a route with suitable space for turns and stops, and plan parking so you can avoid difficult reversing manoeuvres.

After you’ve travelled a short distance, stop somewhere safe and recheck the connection and the car’s restraints according to the supplied instructions. Continue checking them during the trip at safe stops. If the combination feels unstable or a warning light or equipment problem appears, pull over safely and address the cause before continuing.

Frequently Asked Questions

Can I tow a U-Haul car trailer with an SUV?

Possibly, but the vehicle type alone doesn’t establish compatibility. The exact SUV must be rated for the loaded trailer, and its hitch, receiver, wiring and other applicable limits must also meet the requirements. Confirm the specific model and configuration with the manufacturer and U-Haul.

Is a Tow Dolly suitable for an all-wheel-drive car?

It depends on the car’s towing instructions and U-Haul’s compatibility check. Some vehicles cannot be towed with two wheels on the road, so don’t infer suitability from another all-wheel-drive model. If the manual doesn’t clearly permit the arrangement, ask the manufacturer or consider a compatible option that carries all four wheels.

Can I use U-Haul equipment for a car that doesn’t run?

Possibly, but the car’s condition affects whether it can be loaded and secured. Tell U-Haul if it won’t start, steer or roll, or if it has damage, and ask whether the selected equipment and loading process can accommodate it. Confirm this before reserving or travelling to pickup.

Does U-Haul confirm that my tow vehicle is safe for the load?

U-Haul can help check equipment compatibility and rental requirements, but that does not replace the tow vehicle manufacturer’s ratings. You still need to verify the loaded trailer, hitch and vehicle limits for your exact setup. Don’t proceed if the figures conflict or remain uncertain.

Do I need a brake controller for a U-Haul car towing trailer?

That depends on the selected trailer’s braking system, your tow vehicle and any applicable local requirements. Ask U-Haul which braking equipment the rental uses, then verify whether your vehicle needs additional equipment. Don’t assume the answer is the same for every trailer or tow vehicle.

Before you rent a U-Haul car towing trailer, confirm the exact vehicle pairing, loaded weight and hitch setup, then check the rental terms and insurance. If any part of the combination fails a manufacturer limit or remains unverified, choose a different transport method rather than attempting the trip.
