ABSTRACT:
A height adjustable hitch assembly. The present invention provides a trailer hitch assembly mountable to a receiver hitch of a vehicle. The trailer hitch assembly includes a vertically extending channel member having opposing side flanges. Each of the side flanges includes equally spaced holes. A locking member having two pins spaced from one another the same distance as the holes in the flanges secures a hitch assembly to the channel member at a desired height. The height can be quickly and easily adjusted by removing the locking member, moving the hitch assembly to the desired height and reinserting the locking member. The channel member and the dual locking pin minimize rocking, swaying and pivoting of the hitch assembly relative to the vehicle.
