I worked on the bottom of my OFF-ROAD version PUPUP rerouting all of th wiring and getting all of that inside PVC CONDUIT TUBING that runs in an enclosed loop circle under the trailer.
I used the idea of using PVC ELECTRICAL boxes mounted upside down under the floor and drilling a large hole through the center of the PVC box to get back inside the trailer in a cabinets etc... This sealed up all of my large gaping holes under the trailer where things crawled inside from.. ALso made it very easy to add more cabling. You can just take down the weather tight sealed lids on the electrical boxes and pull wire to all places with ease.
The PVC Electrical boxes have the conduit connections for all of the underfloor PVC CONDUIT tubing... Everything enclosed inside the tubing...
It also was a good time to replace all of my DC wiring with good marine type approved two conductor wiring cables everywhere. even labeled a few of them... You know how it goes once you get everything opened up that is a good time to think about all of the things that would be nice to do. Being a OFF-ROAD guy as well as a Radio ham guy we are always doing something with wiring.
I kept dragging off wiring running back in the off-roads before and no problem with that now.. I even redid all of the basic trailer DC wiring for the brakes and lights as well including them in the enclosed PVC conduit paths.
I did all of this laying on the ground outside over a couple of month of playing with it. Sure would be alot easier if it was inside a barn or a garage.
My floorplan looks something like this now (tent beds ends not shown)
I rewired for a more modern WFCO POWER DISTRIBUTION setup with many circuit breakers and DC fuse locations sort of identified in this pictorial..
This is the way I look camping off-road up on a forest road trail somewhere
Love my OFF-ROAD camping...
