ABSTRACT:
A trailer hitch (20) for attachment onto a motor vehicle for pulling a trailer. The hitch (20) consists of a pair of forward and aft mounting brackets (22and24) that are connected into existing holes in the vehicle's frame. Each mounting bracket has flanges (22′ and24′) with the aft brackets (24) having thru-holes (26) arranged in a bolt circle array. The pair of forward mounting brackets (22) are connected to the aft mounting brackets (24) for length adjustment of the trailer hitch relative to the hitch position on the motor vehicle. The height of the trailer hitch (20) is regulated by the right side up or upside down position of the aft mounting brackets (24) properly orienting the thru-holes. A box hitch (44) is adjustably attached for width regulation onto the thru-holes of the aft mounting brackets (24) by inserting arms (30) into a tubular sleeve (50) of the box hitch at an appropriate distance. A receiver box (48) is connected on the bottom of the tubular sleeve for receiving a hitch ball mounted on a trailer ball mount.
