ABSTRACT:
A device for assisting the driver of a towing vehicle to maneuver the vehicle toward a vehicle to be towed to position the hitch members of the vehicles in precise alignment. The device includes a vertically extending sighting rod carried by an articulating arm assembly mounted on the towed vehicle and a stop member mounted on the towing vehicle. The sighting rod is aligned with the vertical axis of the cooperating hitches and is viewed by the driver during backing with respect to an index marker so that the cooperating hitches can be maneuvered into precise alignment. Additionally, the sighting rod permits the driver to accurately judge the closing distance between the vehicles.
