A trailer-hitch-viewing mirror tool that can be temporarily mounted on the tailgate of a pickup truck or the rear window of a station wagon, camper, or other towing vehicle. It easily adjusts to pickup truck's tailgate or other towing vehicle's rear window and can be utilized by anyone without special skills or instruction. It conveniently allows the driver of the towing vehicle to align its hitch ball to the mating trailer hitch socket by affording the driver a clear view of the hitch parts from the driver's seat. The driver slowly backs up while viewing the mating hitch parts through the tailgate or rear-window-mounted mirror, whereby he or she can align the hitch ball to the mating trailer hitch, completing the task quickly, comfortably, and without assistance.
