X2 on finding RATS NEST wiring techniques... Seems like all the trailers have this. Makes you want to SCREAM !!!!!...
The bad thing is it would not take that much more effort to do it right....
Great pictures and drawing ... Wish I had VISIO or AUTOCAD LT haha... I use the only good FREE drawing program I could find called LibreOffice 3.4 which has a pretty good library of drawing components with it... It at least saves the drawings in JPG or PDFs
Good job showing what you got to deal with... I love projects...
I re-wired my OFF-ROAD POPUP to give me smart-mode charging, more batteries, bigger battery cables, Pure Sine Inverters, LED lights, etc. All of my underside wiring between the different cabinets and other points inside the trailer was done using under floor mounted PVC electrical boxs with weather tight covers etc and interconnected with 3/4-inch PVC tubing. My problem was pulling wiring under the trailer from underbrush pulling my trailer back in the woods. Its is all sealed up now and i can fish new wiring from all the points inside the cabinets now with somewhat ease. I used BLUE SEA marine components every where I could. We can stay out off the power grids for long periods of time running off my 255AH battery setup by plugging my trailer shore power cable directly into my 2KW Honda generator every morning for 2-3 hours of generator run time to rechage my batteries back to their 90% charge state.
Very successful for us now camping off the power grids. We actually run just about everything we would run at regular camp grounds except the air conditioner. Kinda neat to just run an 120VAC extension cord to anything we want to run around the camp site.
