We've made a new electrical diagram and will be running both 12V and 120 wires as I go and we open up areas. Plan on putting a porch light of some sort and that will need some wiring.
As we work our way to the back, I plan on replacing all the cross roof braces with wider ones after each panel goes up. Everything will get insulated with newer and better insulation then a vapor barrier and the tin goes back on. I've been working on the doors and drawers and they are almost done.
