My thoughts were on days when very hot to use a invertor generator to power the Air Conditioner on the 2nd leg.
ELECTRICIAN here. NO, do not attempt.
I can do something similar, but you may feel it is too expensive.
My setup: shore power is standard 30A with an additional 20A from my inverter. That requires a 3,000W Victron Inverter and a correctly sized battery bank. I would not try it with Lead Acid, only Lithium. If you NEVER boondock, then a single Battle Born or Lion will do, but if you do boondock even once, then 4 to 6 depending on your energy requirements (audit). You will also need a Victron battery monmitor, a GX device of some sort, BIG welder cables for the 200A battery draw plus misc marine grade connectors, bus bars etc etc. Altogether several thousand dollars. OR go someplace cooler.
