Abstract
A trailer hitch alignment hitch system uses height adjustable stanchions with length adjustable arms terminating in mirrors. The stanchions are respectively connectible to a tow vehicle and a trailer and placed so that the mirror is aligned vertically over the hitch connection component of the tow vehicle and the trailer and adjusted so that the respective mirrors are at different heights. The tow vehicle operator backs the tow vehicle until the mirrors visually indicate vertical alignment by one mirror coming into place below the other mirror and obstructing the view of the hitch component.
