Does you RV have a 50 amp plug?

A 30amp service is 120V.
A 50amp service is 250V (really two 120V circuits with can provide 240V for the AC units.

If you look at your breaker panel, are the AC breakers "ganged" (two breakers for each AC unit).

Check your 12 v disconnect switch. The AC is 120 v AC but the thermostat is 12 v dc.

Is your coach wired for 50A service? and have an Energy Management System?

An EMS monitors the amps available (connected) & will come 'alive' when you have less than 50A service connected. It will then turn off some ac systems (most notably an air conditioner or two) if your amperage demand exceeds what's available.

BTW, a 50A connection is actually two 120vac legs at 50A each... for a total of 100 amps to the coach.

A 30A connection provides a total of 30 amps to the coach, which may not be enough to run everything else plus an air conditioner.

If some outlets do not work, you might check the breaker on your inverter. I had this problem once, I had to find the diagram of the inverter to locate the small breaker switch.

Suspect list: Assuming you have a 50 amp RV
Park outlet (Is it live.. Been to a park where it was not)
Dogbone adapter
Shore cord
Power inlet (If you have one) and outlet on shore cord (Likewise)
Auto transfer switch (if you got one)
Breaker box
If you have an inverter the breakers on the inverter are NOT suspect, they do not power the Air Conditioer.
Screws loose in breaker box (Many RVers have a few screws loose) also on Power INlet and shore cord outlet.

I once had a shore cord outlet end fall off in my hand.. let me tell you the owner was NOT a happy camper.
Home is where I park it!

Do you have an EMS on the back br wall. It takes some time for the Intellec EMS to process the power coming in. Should display all the major circuits and give a green light to each one of them, one at a time, AFTER it screens the voltage.

Basic troubleshooting. The house needs 12VDC to run most of it's control systems and the lights. There is a big relay that shuts off most of the 12 VDC so that when the unit is in storage they do not run down the batteries. The switch that controls the relay may say store or may say nothing. The easiest way to check how it is set is to unplug the unit, turn on a light and see if it lights. If it does the battery is connected. IF it does not try the storage switch. You will probably hear the relay clunk. Then the light should light. IF not you have a problem with the 12VDC. Fix that so other things can run.

FWIW some units are wired so the converter that changes 120 VAC to 12VDC gets powered when plugged in and some have the converter wired to the battery. The first kind does not charge the battery unless the storage switch in in run mode. The second version needs the storage switch in run mode to do anyting. Bottom line is get the switch in run mode then go from there.
