Abstract
A hitch connection is provided for use between a towing vehicle and a trailer and includes structure whereby slight right and left lateral movement of the forward end of the towing vehicle will not be translated into left and right lateral movement, respectively, of the forward end of the trailer and thereby eliminates the tendency of a trailer to sway back and forth during crosswind gusts and as a result of the slip stream of a large vehicle such as a tractor and semi-trailer combination passing a lighter vehicle towing a trailer.
