I think the easier and more aesthetic install would be to disassemble one of the free standing units designed to vent out of a window via a vent hose. It looks like one could be made to fit behind or under a rear bed venting out behind the spare tire and blowing cooled air into the GMC down the main hallway. The ones we use in our building (no need for AC in So. oregon except for a couple of weeks each year because it nearly always cools off at night) are quiet and do a good of cooling even large spaces if left running long enough. They are also inexpensive enough for such an experiment and the running amp draw is down in the 9 to 12 amp range (use one of the soft start units) so could be run through an inverter with a large enough battery bank or perhaps off of a 15 amp shore power line or via a small 2kw portable generator.

We actually had a 12k Mini Split in our old house that was 110V. It was the largest 110v unit I could get. If I remember it was a Fujitsu.

An interesting approach. We had a couple for emergencies (In Georgia, if the A/C fails you best cool the equipment somehow). It gets a bunch of weight off the roof as well.

Gerry,
I've had that same idea rattling around in my head for a while. We use two of those units here in our home and they are quite efficient. The units we have can also provide heat, so they would be an ideal choice for retrofitting into an RV.

Size is also amazingly compact when you consider that the housing also contains a water reservoir for condensate collection. Once that reservoir is removed, you have really compact AC unit. At 13k btu, the largest components are the Evaporator and condenser coils, which are approx 12"x12"x3" each. With some careful thought, the components could easily be placed out of the way.

My biggest complaint on these units is the fan noise, although very reasonable, it could be reduced substantially by using a larger, slower spinning squirrel cage fan unit. Compressor noise is no more than your home fridge.

We are planning on going to central air in the near future, so the two mobile ac units currently being used will probably be frankensteined for both my TZE, and my travel trailer. I really am not a fan of the rooftop units.
