I would agree on shopping around at trailer dealers and truck accessory places for hitches and wiring. When you do get a trailer, CHECK IT OVER THROROUGHLY. Check the tire pressure, shake the wheels to check for bearing play and look underneath to inspect the axle and suspension. I don't know what kind of maintenance program they have, but I have seen some real ratty U-Haul trailers.
