I bought a champion 3150 inverter. Supplies 26 amps. I bought it because I didn’t want to have 2 units to maintain. It was the biggest one that I could pick up by myself and load in the front compartment. It will easily run one AC unit, the converter, lights & TV all at once. I manage load by using gas on the fridge & water heater when AC is running. I also shut off the AC for a few minutes to run the microwave or coffee maker. This has worked well in temperatures up to 90. I have not tried cooling the unit with one AC at higher temps.
The Champion has been reliable and is not excessively noisy. It has a built in 30 amp camper receptacle.

If you must run 2 AC units, you need either 2 small units or one bigger unit. BUT, before you buy the extra capacity, try operating your camper on one AC and see if one is sufficient for you.
