Cool. Not suggesting you overdid it, I like stuff hardwired too, just no skills to do it right. Hell, I can drill holes and run wires all day but it rarely works as planned!
Added a backup camera to my trailer, when plugged to the truck it replaces the tag camera. This should be useful when traveling and backing. The wiring runs behind the bathroom, refrigator, up the back wall, and into the rear overhead cabnet.
I did replace those 4 1970 solar panels with 2 100W, 36v panels, still portable. Even on a overcast day they will contribute an amp or two, and easily charge the batteries on sunny days.
