Abstract: Pull-Rite is an add-on device that makes a tongue ball and hitch type trailer capable of being towed with a gooseneck connection. The preferred embodiment of the invention utilizes a U-shaped base frame having a ball hitch and a lower support crossbar, adjustable vertical rails, an upper crossbar, upper bars, and a vertical down bar with a slide-in gooseneck mount or a fifth wheel pin. To use the preferred embodiment of Pull-Rite, an individual attaches the lower support cross bar of the base frame to the rear of the A-frame of a trailer. The ball hitch on the base frame is then connected to the A-frame in the traditional manner. The vertical rails can then be maneuvered to the appropriate height for use with a given tow vehicle. The downward vertical bar is then attached to the tow vehicle using the slide-in gooseneck mount or a fifth wheel pin to allow the trailer to be easily and safely towed.
