Back Up cam Whats a good one

[Fireman40]

Ok so im getting tired of trying to hook my truck up to a trailer when Im at a funny angle and having to get in and out of the truck and pulling forward and back again to get it lined up. It easy to do when im straight on with it but thats usually not the case for me. I want to get a good back up cam for a good price. My problem is the ones I have seen go on the Liscense plate. I have a 6 inch drop hitch. My worry is that it wont see down past the bumper to the ball. Does anyone else have a camera for this purpose that works for them?
