Ok so bear with me when you see how the electrical is shaping up in the box. There will only be very light loads on any of the electrical in this thing at any one time as most of the lighting will be LED. The only thing I have not decided if I want to splurge on are LED backup/spot lamps as we usually do get to camp late/set up in the dark.
The outdoor outlet mounted on the bottom of the box has 2- 110v outlets. 1 outlet will run directly off any 110v that is plugged into the opposite side of the box. Probably unnecessary as the post at a campsite with 110v, but I felt it would be a nice option. The other 110v outlet will be powered by the commercial invertor that will be inside the tongue box. I may change this down the road to work 100% off the invertor, it would be as simple as unplugging from the power strip, and plugging into the invertor.
The 12V outlet on the side can run off 110v --> 12v convertor or the battery itself. There probably will be a battery tender inside the box eventually as well.
All but the main switch panel mounted and sealed in place
The 110V, 1 side is from the battery/invertor and the other works when plugged into the pole
