Just to clarify...the newer version of the Dometic 11,000 BTU A/C comes equipped with a smart start capacitor. I successfully ran the A/C with a Honda 2000. I put it through all the paces of starting up under different situations, and it worked fine. It does run into the peak capacity zone when the compressor kicks in, but does not trip the breaker. It would be an issue if the trailer batteries are weak and the on-board battery charger is working to charge them while you are planning to use the A/C. I would suggest switching the batteries off before operating the A/C. Our test had all the LED lights on, and the furnace running. (had to create heat in the winter
) The generator should provide enough power to run basic items in the trailer at the same time as the A/C.
The down side of the new a/c is it is approx 20 lbs heavier than the previous version. (its not the smart start)
Hope that helps
