Recreational vehicle towing means towing the vehicle behind another vehicle - such as behind a motorhome. The two most common types of recreational vehicle towing are known as dinghy towing and dolly towing. Dinghy towing is towing the vehicle with all four wheels on the ground. Dolly towing is towing the vehicle with two wheels on the ground and two wheels up on a device known as a dolly.

Here are some important things to consider before recreational vehicle towing:

    • What is the towing capacity of the towing vehicle? Be sure to read the tow vehicle manufacturer's recommendations.
    • What is the distance that will be travelled? Some vehicles have restrictions on how far and how long they can tow.
    • Is the proper towing equipment going to be used? See your dealer/retailer or trailering professional for additional advice and equipment recommendations.
    • Is the vehicle ready to be towed? Just as preparing the vehicle for a long trip, make sure the vehicle is prepared to be towed. See Before Leaving on a Long Trip.

Dinghy Towing

Two-Wheel-Drive Vehicles


Object Number: 2073531  Size: B3

Notice: If the vehicle is towed with all four wheels on the ground, the drivetrain components could be damaged. The repairs would not be covered by the vehicle warranty. Do not tow the vehicle with all four wheels on the ground.

Two-wheel-drive vehicles should not be towed with all four wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed. To properly tow these vehicles, they should be placed on a flatbed truck or trailer.

Four-Wheel-Drive Vehicles


Object Number: 1235863  Size: B3

Four-wheel-drive vehicles can be dinghy towed if the proper procedures are followed. The transmission has no provisions for internal lubrication while being towed, so it is important that all the steps listed in this manual are followed to dinghy tow a four-wheel-drive vehicle.

Use the following procedure to dinghy tow a four-wheel-drive vehicle:

  1. Position the vehicle being towed behind the tow vehicle and shift the transmission to P (Park).
  2. Turn the engine off, but leave the ignition in the ACC/ACCESSORY position.
  3. Firmly set the parking brake.
  4. Securely attach the vehicle being towed to the tow vehicle.
  5. Caution: Shifting a four-wheel-drive vehicle's transfer case into N (Neutral) can cause the vehicle to roll even if the transmission is in P (Park). The driver or others could be injured. Make sure the parking brake is firmly set before the transfer case is shifted to N (Neutral).

  6. Shift the transfer case to Neutral. See "Shifting into Neutral" under Four-Wheel Drive.
  7. Release the parking brake only after the vehicle being towed is firmly attached to the towing vehicle.
  8. Turn the ignition to LOCK/OFF and remove the key -- the steering wheel will still turn.

After towing, see "Shifting Out of Neutral" under Four-Wheel Drive.

  6. Shift the transfer case to Neutral. See "Shifting into Neutral" under Four-Wheel Drive.
  7. Secure the vehicle to the dolly following the manufacturer's instructions.
