Running wires - how do I do it best (and neatest)

Holes were originally drilled through the camper framing for the wires.

Here is a picture of our Yellowstone project. It shows the 12V running light, brake light wires, as well as the 12V interior wires for a few sconces.


This one shows all of the 120V coming into one central location for the breaker panel.


If these aren't helpful, let me know what you are wanting and I will look through more of my pictures.

TOW WIRING:

I run mine under the trailer, starting at the front J box and sometimes placing one under the bed as well. From the back, I run the wires inside the back wall to the tails. Since my trailers usually only have back clearance lights, I sneak a wire from each tail to the cl. light.

12 volt wiring is pretty small, so it's easy to wire front clearance lights as well. A 5/16 hole is usually enough to accommodate a ground and hot.

Last thing, you don't necessarily need a ground run from the front to the back, as the entire trailer frame is a ground. You can bolt at the front and the back for each ground.

Well, I've been there with the RATS. Dratted rats. They ate my car instead of a trailer. Lucky for them.

I say under the trailer makes it easy to do repairs. Damned if you do, damned if you don't...

I ran mine in a cheap, $2 piece of 1/2" PVC pipe.  It zip ties to the frame and the wires are mostly protected except for a few inches at the front or back.

To drill holes in 3/4" thick framing, I used an angle drill bit holder and hex drills.  It's a little floppy and hard to start, but you can guide it and once it bites in, it will stay straight.

I was not a fan of drilling little holes through that framing yesterday, that's for sure. Got one side done. I tried staggering the run and kept it low. Will brainstorm ideas on how to keep track of wires behind walls. Maybe a good map for future reference will be good - pictures and measurements.
Going to run the 12V tow lighting (clearance lights and such) underneath and up through the back of frame and through the walls. All the 12V (except the fan) and 110V wiring will run inside. I only plan for 2 (maybe 3) 110V outlets and a small DC power station (USB, Voltmeter, plug).
I've dealt with mice and rats before and I know those little bastards will eat ANYTHING. My underbelly is primarily wood so it'll require pretty frequent routine inspection and upkeep. I'll inspect for critter damage before heading out on the road.
I debated on running individual grounds for my clearance lighting, as I've seen others do, but I decided to have faith in the metal trailer skin - thanks Vikx.
