Air Conditioner Installation DIY?

I installed one myself,a replacement so no big deal. The camper we have now is old and came without one, however it was wired to the center vent, had a 12V fan in it. Had mobil camper guy come remove vent and install that one. That was after the first one came with a damaged drip pan and a few bent vent fins. Dealer said to trash it and sent me a replacement. Other one still in my shed as I couldn't bring myself to trash one that could be fixed and is brand new otherwise. Anyway they are the Coleman 9200 low profile, Polar Cub, Mach 8 whatever. Honda 2000 runs it fine, but not a microwave at the same time. Just be sure that the factory wiring isn't spliced in the wall with the cabinet receptacle for microwave or you'll blow breaker same as you would overload the Honda. One on one off same as with the genny. Ours is like that we discovered when adding individual breakers to converter to separate them. There are two receptacles up front that are wired on a 15 amp breaker, fridge on that one. May be able to get away with using one of those outlets for the micro then the separation would be there. Not up for major wiring overhaul and expenses for what is really a minor inconvenience for us.
