Trailer a device that makes it possible to tow a vehicle with all four wheels totally off the ground.
This eliminates concerns about transmissions, odometer mileage accumulation and backing into campsites, but loading and unloading can be cumbersome and time-consuming. The motorhome owner also must find a place to store the trailer upon arrival at a destination.
