ABSTRACT:
A hitch for coupling a trailer to a towing vehicle includes a first coupling means for coupling with the trailer at a pivot point and a second coupling means for coupling with the trailer at a towing point. A displacing means is responsive to pivoting of the trailer with respect to the towing vehicle to move the hitch and the pivot point on the towing vehicle toward the rear of the vehicle when turning is effected and to move the hitch and the pivot point on the towing vehicle just forward of the vehicle's rear axle during normal longitudinal movement of the towing vehicle and trailer. The second coupling means is capable of transferring at least the majority of the towing force between the towing vehicle and the trailer.
