It doesn’t take much of a generator to sustain even a 13.5 a/c unit. The issue is the draw at start up. I use dual 2000 watt Honda’s paralleled on mine. For an easy quick weekend away the Tucannon valley has a primitive state campground, several state pull out type campgrounds and the Last Resort campground has full hook ups and are good folks.
I spent some time on the Tucannon years ago; there used to be a joint called the Tucannon Fireside where we got seriously good burgers! Wonder if it is still there?
