"AC only runs on 220v"??? I would think this is not correct. The owner is most likely looking at the shore power cord plug, and seeing what looks like a 220 plug used for an electric stove and thinking its 220V. But the shore power cord is a 120V 30 amp plug. Or if the AC is a side mount AC unit, he is looking at a 110V 20A plug and because it is different than a standard 110 plug thinking it's 220V.

Just ask him if the AC runs off the campground camp site power. It is does, it's 120V. I'm am not aware of any campground that has 220V at the camp sites.

PS just read bill's post. we must have been writing at the same time. I like his idea to pull the cover.
