ABSTRACT:
Improvements in trailer hitch apparatus of the type used in heavy hauling, particularly for the transport of mobile home structures. The apparatus includes hydraulically elongatable tongue structure with height adjustable connector ball assembly as supported from the main rear truck frame structure; the apparatus is utilized in combination with a leaf-coil rear wheel spring structure that provides primary truck suspension. The trailer hitch is operable to support its towed structure in any of the open or closed elongated positions in order to better enable certain vehicle maneuvers, achieve optimum handling in emergency situations, and provide a more rugged, yet smoother riding connection to the towing vehicle.
