Installed the wireless back up camera.....
I bought this monitor from Amazon a while ago and installed it in the truck with a camera over the liscence plate to aid in backing up and hooking up....$38
For the trailer, I bought this camera on Amazon...$17
And to get the camera from the trailer to feed the monitor in the truck, I went wireless with this device.... $12
The camera was mounted above the center clearance light and was powered from this light.
The wire ran over the roof to the siode of the AC unit where the transmitter was located, under the AC cover, out of the weather
The "receiver" was simply wired up under the dash and connected to the second camera input on the TV monitor
The top screen is the RV760LMT GPS unit. The bottom screen is the rear camera. This screen slides into a "Drawer" when not needed...
Works fantastic and I love the fact that I didn't have to run a wire the length of the trailer and another wire from the trucks dash to the rear of the truck.
Added shut off valves to the fresh water drain and the two "low Points"
More better than the little caps I needed to crawl under the trailer to remove. These I can simply reach between the tires and open or close....Nice!
