Trailer

A trailer is an unpowered land vehicle towed by a powered vehicle, commonly used to transport goods and materials. The two general categories are full trailers and semi-trailers. A full trailer has its entire weight supported by its own wheels, while a semi-trailer transfers some of its weight to the towing vehicle. Some recreational vehicles, travel trailers and mobile homes have also been called trailers.
