best way to run residential fridge on limited shore power?

I have successfully run two ACs occasionally on 30 amp. I would never leave the MH like that as the breaker could kick and the dog would suffer.

Expect the breaker to trip. Typically at a bad time even with almost everything turned off.

Some locations I can not even get 2 ACs working at all.

water heater, and norcold need to be on propane. Battery charger as low as possible or off during the day and charge the batteries on a low setting when possible.

I do not like 30 amp in spring or fall, but hate it during the summer.
