The wire for our camera runs through the roof. To run a new wire, probably the best way to do it would be to run it under the motorhome. You would need to find a way to get it through the firewall in front, and you would need to run it behind the cap in the rear. I have watched Tiffins being built, so I know there is a space behind the rear cap. However, there is a foam baffle that runs across the rear cap to keep air and critters out. If your rig has something similar, you would have to find a way to get the wire past the baffle.
I have also seen wireless cameras, but I don't know how reliable they are.
