How to run exterior cable for wired backup camera?

[bighatnohorse]

I'm planning to use a hard wired backup camera for my RV.
There is NO CONSTANT DC voltage available at the RV back and I want to enable the camera at will from the truck cab.

I've done this before on a previous camper but think that I could make a cleaner, neater job of it on my new camper.

My question is regarding exterior cable management.
What might be the best way to mount the video cable, running from the rear of the RV to the front?
(Approximately 27 feet).

I have a wireless backup camera but if I was to have a wired camera I would either use the RV's tail lights, back up lights or run conduit along the frame for power.

I don't know if it's best, but one reasonably decent way is to put the wires in a length of split loom tubing, and then attach it to the frame underneath with zip ties at intervals where possible. If you can thread it above the frame or otherwise through a more protected place, so much the better.

The split loom tubing helps protect the wires from the elements and from being crushed with the zip ties. One source of it at pretty reasonable prices is All Electronics, although if that's all you get the shipping and handling will exceed its cost. (Incidentally, they also stock Delphi WeatherPack connector kits at pretty decent prices.)

Try to run it in the frame rails underneath all the way up to the firewall and then into the cab
