They do have cameras that connect to a wireless transmitter. You can run the wire from the camera to the front of the RV where it can transmit to the monitor inside the cab. I wanted something I could connect to my existing radio screen, so I ran wire up to the hitch, and connect there to 2 wires that go to the engine bay and through the firewall to my radio. I'm ready to run a heavier, fused wire from the battery into the cab for radio and camera connections. They are running off of auxiliary now, and I'm not wanting to overload that circuit. My trailer came with the pre-install for the Furrion wireless camera. I bought one, and sold it. It was too small and wouldn't work with my radio. So I used power from there to run my $35 e-Bay camera, that is mounted to the pre-install mount. I run the video wire down the back of the trailer, in colored molding, and underneath to the hitch. It works for me. I don't use it as often as I thought I would. I use it to help with backing, and to occasionally check traffic behind me, but I spend most of my time with the GPS and map up on the screen.
