Question about 30 amp vs 50 amp service
So, assuming I some day get my rv back from the shop and can actually go somewhere in it, I have a question about the electrical. I've had a class C in the past with 30 amp service and it had the typ...

A lot of motorhomes built before 2000 model year had 30 amp service to them. Even if they had two air conditioners. So my guess is that you should have a 5,500 watt generator rated to run both A/C units. The 30 amp service probably will run one A/C at a time, and might have a 'energy management system' to shut off one compressor at a time, and run both fans all the time.
My buddy's 1985 class A DP had a switch in the back to run either the front or rear A/C unless the propane generator was running, when both A/C's could be turned on at once.
If you have a 5,500+ watt generator, then it should have a pair of circuit breakers, typically a 20 and 30 amp breaker. The 30 feeding the main panel, the 20 feeding a relay with just one air conditioner on it.
It is possible, and not all that difficult to upgrade your RV to a 50 amp service. Back in the late 90's Weekend Warrior used to offer a dealer installed optional 50 amp service. Basically it was a 50 amp panel installed in a storage compartment, with a 50 amp main 2 pole breaker, 30 amp feeding the factory installed panel and factory power cord, Then a 20 amp was run to each air conditioner and another 20 amp breaker fed the receptacles near the air compressor in the garage area.
It might take me 45 minutes at Home Depot gathering the supplies, and another 2 hours to install it all in the storage compartment where the electrical cord is located, perhaps another hour if you wanted the electric panel in another compartment.
Good luck,
Fred.
