The big key is to ensure FIRST that the voltage to the unit stays up when you are running these things, and then second, the amps do not exceed what your breaker is rated for.
I agree. However, if your AS is parked very far from the house and you have to use an extension cord, you will have a voltage drop that can cause damage to the A/C unit or you can simply add up to too many amps and trip the breaker during the start-up of the compressor.
It all depends on what is connected to the circuit other than the Airstream. Ideally, you should have a dedicated 30 amp circuit to plug the Airstream into. If you don't you run the risk that you may not have the volts to run the A/C or you will keep tripping breakers or damage the A/C.
