I used a license plate camera instead of the one that came with the monitor. Used the power from the license plate light and I have to have the running lights on to get a monitor signal. The monitor is a little dash mounted thing that I plug into the 12 volt dash outlet. I ran the cable inside the rv under the couch behind the closet through the bathroom cabinet behind the toilet under the shower etc to the rear floor wher I drilled a small hole for the video wire. That wire just attaches to the camera and is visible. But it did the trick for very little investment. I only use the system when I think I need the extra visibility.
