I got one of those license plate ones. Used the towing hitch and ball to aim it and now i know how close i can get. good for hooking up a trailer too. Also it has a fish eye lens so you can also see things that are up higher. Got it on amazon for like 25 bucks and hooked it up to my DD. Wife loves it, cus she can park the Yukon in reverse at the mall. Looks good at night too because it has night vision. When it warms up im gonna mount it on the bumper, between the bumper and hatch door. Theres enough room there. Gonna use some double stick tape. This is so it wont get stolen or kids mess it up.
