demco has good auto sliding hitches, I don't suggest anyone with a short bed use a non- auto sliding style hitch. It will most likely save you a trip to the body shop and the glass company for a new window. If you ever upgrade the truck to a long bed then I would get a trailer saver air ride hitch. The ride in the truck is much nicer than a hitch with a hard connection.
