Because of some mobility problems, I could not crawl under the MH, or up the back to where the top marker lights to install a backup camera. My only option was to install them looking through the back window. I don't have a picture to post at the moment, but the installation turned out way better then I expected and ended up with two cameras.
The cameras are mounted one above the other on spacers mounted on a 3/4" aluminum angle riveted to a 2" square of 1/8 aluminum. The bracket is about 6" long and screwed to the wall, the 2" square is the mounting plate to the wall next to the rear window.
The rear window is offset so the edge of the window is centered on the rear wall. So the bracket just had to extend from the wall past the edge of the window. We have a rear kitchen so I ran the wires for both cameras up about 6" into the cabinet, out the cabinet and along the ceiling past the bathroom into cabinets that ran to the front, then down to the floor behind the driver's seat under the plastic panel in the step-well, and under the dash.
I used 3/8" wire mold from Home Depot with splices and corners where the wire appeared on the ceiling between the cabinets, and down the wall behind the driver's seat. The wire mold had a sticky foam back and stuck solidly. The wires are all hid and it looks professional. In my past life, I ran hundreds of feet of wire mold for data lines, it is not hard. Don't use this stuff on any thing but a smooth surface, it won't stay stuck.
In the dash, I mounted a small switch in the trim of the new Kenwood do everything radio I recently installed. The switch selected the camera I wanted to look at. The lower camera pointed down at my cargo hitch carrier holding my mobility scooter, and the other straight out the back. The line from the dash switch feeds the video input of my Rand McNally GPS. It works really well.
I bought the wide angel (130 degrees) cameras and cable from Ebay. I cut the ends of the cables off that I ran to the front of the motor home wired them to the switch and the power line to the switched lead feeding the radio which I did not use because I wanted to listen to the radio with ignition off.
I'll get a photo of the bracket and post it here as soon as I can.
I bought the mirror that fits over the rear view mirror. Did not work well, sun light blanks it out, could hardly see the video. My GPS was way better video. It sits in the box now.
