I think I've got everything electrical in the trailer identified now.
The AC panel has 6 breakers.
1 - Main
2 - A/C, which doesn't actually even have a receptacle installed
3 - Portable appliances, plug over kitchen counter
4 - Front two plugs over the couch and one near the kitchen counter on the driver's side
5 - Exterior, entrance, table, bedroom and bathroom plugs
6 - Fridge/Microwave plugs.
The fridge/microwave plug powers something in the converter unit that makes a humming noise. I'm guessing its the battery charger but am not really sure.
There are labels on the front of the converter, but they aren't correct at least on the AC side, not sure about the DC side although I know there's at least one extra fuse that has no label at all.
So I should be able to disconnect the wires from 3, 4 and 5 and run them right to my inverter. Then even if by some strange weirdness we were teleported somewhere else with shore power, or I wanted to run the generator and plug the trailer into it, it would only power up the battery charger, assuming it's the 'hum' I hear.
