If you expect to hardly ever use this system, Option 4 is best. If you want it to run every time you run the engine, option 2 would be the best way to go.
Thanks for the ongoing tips and teaching!
I think this will be my best bet, and may also double as the input switchover reminder too, if I don't figure out how to switch the inverter input from this setup to house battery draw for 240v output without a plug swapping shuffle...
