One 15 amp for refrigerator and microwave. ( when boondocking on 12v and solar, refrigerator with be cooled like and ice box refrigerator with blocks of ice)
20amp in the kitchen because it may get a heater or even AC unit plugged into it down the road. A propane heater buddy will be used when on 12v with no shore power. ( For cooling there is a fantastic fan vent on 12V)
One more 15amp for three more plugs on GFCI. Total of 5) 110AC plugs and 4) 12v plugs with two USB ports and one Cigarette lighter ports, plus two USB ports on controller. 12v will run water, radio, fan, lights and all DC plugs. This is a must have for charging photography camera batteries and such. Most of the time will be on 12v and solar. All of the electronics work on 12v as well as 110ac.
Had a real duh moment with the wiring. So much thought and planning goes into these conversion and takes up all my brain power, not that there is a lot of it.

Anyway, was thinking just wire the whole trailer from the center on the ceiling.
After I got everything in place it hit me about summer heat and the roof metal getting hot.
There is a little space between the ceiling bars and metal roof in the center where they put wood down to give a little arch. So that is where I went with the wire and ended up changing it all out so nothing touches the roof now. The 12v wire is very easy to work with. 12 gauge is what I used on the 110ac side. Not as easy to work with but not too bad.
One of my biggest dilemmas has been finding the right holesaws for some of the plugs. The 30amp worked well with a 3″ holesaw. The satellite cable was a simple drill bit but the solar plug I am still having trouble finding the right size. Home depot gave me a 3/4 inch bit but it would not even fit in any of my drills. So back to the drawing board and YouTube videos.
Another dilemma was finding a flex hose to fit under sink drain from 1 1/2 into water cooler bottle. Turns out I found this simple baffle solution at Lowes. Fits perfect and is very sturdy. The baffles expand and contract as well as bend.
Next is clear coating and putting the birch on the ceiling. Still looking for the right holesaw for puck lights. Says 56mm but could not find any at Lowes or Depot or anywhere for that matter . If you have any suggestions please let me know.
Anywho... thanks for following along... as the beat goes on...
