Abstract: The receiver hitch assembly includes a receiver permanently attached to the towing vehicle and a drawbar removably attached to the receiver. The receiver and the receiver attachment end of the drawbar are oriented vertically, the receiver and its mounting structure being configured for concealment by the rear bumper or other structure of the towing vehicle when the drawbar is removed. The drawbar is configured to clear the rear bumper and/or other structure of the towing vehicle when installed to the receiver. The drawbar is also configured to position the hitch ball at approximately the same level as the center of the receiver when the drawbar is installed. The drawbar may include a longitudinally telescoping center section to allow the hitch ball to be spaced from the structure of the towing vehicle for clearance, load distribution, or other reasons.
