I put the following on my 5th:
Back up cameraI think it says back up camera, but we used it for 3 weeks from Michigan to Montana and back, always on (to watch our bike on our swivel wheel). Never a hiccup.
It's made for much harder use than us RVers.
I decided to attach the camera to the ladder with some small cut pieces of rubber (to protect the ladder) and then black zip ties. I can then easily remove it and it unplugs from the remainder of the wire harness at the back of the trailer.
I ran the very long harness under the trailer, wrapped in split tubing and into the front storage compartment. Because my trailer has an inner and outer metal sheeting, I ran the end of the harness back out the bottom, created a holder that I screwed into the bottom of the trailer and attached the end of the harness to that.
I then got a 1 inch hole saw and drilled a hole through the plastic (yes, plastic) rear bumper of my F350. I put the connector and wire through the hole and that leaves the metal connector bolted (two additional small holes) to the bumper (between one license plate light and the license plate).
I then ran the cord under the truck, first encasing it in cable wrap, then zip tieing it to various spots under the truck along the outside of the frame.
Now on my truck, there is a rubber plug under the back seat about 2 inches in diameter. Pulled that plug and your looking right at the carpet underlayment. Mine came up under the sub woofer, but was accessible. Careful not to poke into the subwoofer, my wife used a awl to poke a hole through the underlayment and carpet (me with my hand under the subwoofer to ensure it wasn't damaged). Then she used quality sheers to cut an x in the material. I put an x in the rubber plug, ran the wire through everything, drawing the excess wire into the truck. Using silicone sealant, sealed the cut in the floor and the plug.
Looped the excess wire and ran it to the monitor.
I used one of those cigarette ashtrays for use in the cupholder, put a piece of rubber on the top and affixed the supplied monitor holder to that.
Power supplied from a 12 volt outlet in the truck.
