It's the start up watts that is the problem, so I'm going to say no, but maybe with/if a hard start capacitor is installed in the 10,500 BTU AC being used in the new models. You wouldn't be able to run/start much of anything else though. I would look at the Yamaha EF2400iSHC. Only weighs 75 lbs. With a Class B's lack of storage I would go with the built in. http://www.yamahamotorsports.com/powerp ... /home.aspx
