Just for clarity, here is the wall section. I am taking about filling the hollow area.
My door showed up, but the UPS guys had their way with it
, edges are good and dented in a few places....
Picked up a used inverter/charger as well, only 1250 watts, but should run a microwave (i hope!). Charges at 55 amps, a bit slow there as well, but the price was right. Came with a 200A Blue sea breaker too.
