Abstract
There is disclosed a modular trailer hitch and tow bar having multiple coupling points at which the trailer may be separated from its towing vehicle. The first is a pivoting coupling on a vehicle mount unit near the horizontal axis of the towing vehicle rear wheels. The second coupling is rearwardly displaced from the first and is a sleeve and bar coupling which is normally used to separate the tow bar into a trailer connector unit and a vehicle mount unit. The third coupling is rearwardly displaced from the second and is arranged to conform to the juncture of the bifurcated arms of a conventional travel trailer tongue. The third coupling operates in conjunction with clamps engaging the tongue to form a rigid and rugged joinder of tow bar to trailer tongue arms. A vehicle mounted tow bar holder holds the truck mount unit portion stationary when the tow bar is disconnected at the second coupling. In one embodiment the tow bar forward of second coupling is telescopically adjustable to allow for different vehicular lengths.
