Victoria got me an iBALL Wireless Trailer Hitch Camera for Father's Day. Initial test looks good. Haven't used it yet to hitch the TT and TV. However, tested it this morning on the TV. Very easy to use. Simply put the 9V battery in the camera, and use the magnet base to attach it to the tailgate of the TV. Plug the receiver into the cigarette lighter of the TV, and turn it on. The result is a wide-angle color picture of whatever is behind the TV. The camera can be angled so it points directly at the hitch, or straight out for a wider view. So far, I like it! It seems about as dummy proof as it can be - which helps me a lot.
