A/C can only run by itself, anything else trips it

We are now in Southern Texas and it's already a 100 degrees. Fifth wheel 33 ft with one middle a/c unit and 30 amp. I am packed in shade. It's not keeping very cool except in middle near it though ...

Which breaker is tripping:
The A/C Unit circuit breaker?
The RV's Main 30A breaker?
Or the power pedestal 30A breaker?

Bad breaker.....
Overloading circuit....
Low AC voltage....do you know what the incoming voltage is?

Run fridge on propane, run water heater on propane

Solar will only help you charge battery.

One A/C unit in 100*F PLUS temps....tough to keep 33' rig cool
Heavy load on A/C unit..especially if it's just a 13,500btu unit.
