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?

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

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.)

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 know you are specifically looking for a wired backup camera, but I can't help but throw this out there.....

You can get a wireless backup camera and monitor for ~$150. Since you probably want to mount the camera up high, you likely (right??) have rear upper running lights. You can tap off power from those and mount the camera right under the running lights. Then, to "turn on the camera" from up in the cab, all you need to do is have your running lights on. (Personally, I always drive with the lights on just for extra safety/visibility).

Time to complete the job...less than 1 hour.

If you mean to use it as a rear view camera besides just for backing up, you can switch the power to the camera or leave the camera on and switch the display.

Our camper has a "porch light" by the back door that can be left on to tap the camera's power into for constant 12v.

I don't know a good way to get the video wire to the display in the truck. I have a Hopkins wifi camera that works great and displays to your "device" when you select the Hopkins APP. You just put the "device" on your rear view mirror with elastic bands and good to go.

This one has those two guide lines you can select when backing up or leave off for driving. The camera also has a light you can select. The wifi works up to 40 ft so not enough for a 5er, but could use a booster in the front of the trailer. No issue with a truck camper for distance.

There is a time delay which you have to get used to, so you see a car starting to pass and he is already beside you. something to do with "processing time". I don't know if that happens with a wired system.

I tap off the bath fan (I have a rear bath). Mount a on/off switch near the fan with a pilot light. Run the cable through the vent cover.

I like this idea. We tow and I'd like to keep an eye on the tow vehicle AND have the truck power the camera. This would work.
I'll think on it for a while. . .lots of other good suggestions to consider.

Yup, i wired mine to the running lights also. Makes a world of difference for changing lanes. With even a cheaper camera , you can see enough. Even at night in storms, you can see the headlights behind you. Tbh, got it as a backup camera, but never use it for that. Just to used to the mirrors. But it still has a purpose.

Use this until you get to the bottom where you can follow the brake/turn signal wiring. It looks clean, easy to install, and can handle the elements.
