I have two cameras, both hard wire.
One is a plug and play backup camera from Camera Source, and works just like the stock camera mounted in the tailgate and is activated when the truck goes into reverse.
The second camera is also hard wired and is for viewing the trailer a pull with my SXS, which is very difficult to see when the camper is on the truck.
This camera, and monitor cost $65 at amazon and works continuously while turned on in the cab of the truck, so I can easily see the trailer and SXS.
I have both plugs set up behind the license plate of the back bumper.
