Camco's Magnetic Hitch Alignment Kit is designed for one-person hook-up on the first try every time. Easily visible balls take the guesswork out of linking up your hitch. Attach one guide to the tow vehicle and one to the trailer. Guides extend to 50 inches for easy viewing, and a swivel base allows the guides to be positioned directly above hitch and receiver. This system works with virtually any tow vehicle and any trailer: gooseneck trailers, fifth wheel trailers, horse trailers and boat trailers.
