Different types of hitches are used for towing trailers behind vehicles, including pintle hitches and fifth-wheel type hitches. The pintle hitch uses a pin or ball near the rear bumper of a towing vehicle to interlock with the trailer. A fifth-wheel hitch is usually supported within the bed of a pick-up truck for the purpose of distributing the load from a trailer over the axle of the towing vehicle. Trailers configured with a pintle hitch cannot be attached to a towing vehicle by means of a fifth-wheel hitch, and vice versa.

Naval Surface Warfare Center, Crane Division, has patented and prototyped a universal towing configuration that enables a trailer to be attached to a fifth-wheel or pintle mount.
