KING PIN ADAPTOR, HITCH ASSEMBLY, AND TOWING SYSTEM

A king pin adaptor is provided for allowing a king pin, intended to connect to a fifth wheel hitch, to be attachable to a ball hitch assembly. A ball hitch assembly is provided having a plurality of vertical and longitudinal positions for securing a ball member to allow for greater flexibility in attaching to various towed structures. The king pin adaptor and ball hitch assembly may be used alone or together as components of a towing system for towing a trailer with a king pin or ball mount.
