I know your talking about back up cameras but when I get my lift and bigger tires with the full size spare tire on the back I have been looking into getting the RubiCam Camera. Its a live feed system basically like a rear view mirror and it comes with a display screen. you could get a non dvr version and the dvr version up to 4 cameras on it. I am planning on using it for my full time rear view mirror and completely replacing my rear view Mirror.
