the controls for the ACs look to be factory. and Wa8yxm you're probably right. This rig does not have a transfer switch, just the ole fashioned plug the shore power cable into the generator outlet. When we ran the things before delivery, first we ran on shore power and the guy demonstrated the load shedding. One or the other but not both would run depending on the temp settings. We then ran the generator and both ACs would run... heck, who knows, I might have knocked the ckt. breaker to the off position while cleaning up the generator. Guess this has been much ado about nothing --- but now I know before I need to use AC.
