Thanks for the responses. Yes, it is a 120 not a 240 and includes the heat pump. The other option I had was to install two window units in cabinets. The microwave under the cooktop is useless to us and it would make a great front area location. The bedroom cabinet would be over the bumper and into the wall. The window unit idea sounds very complicated and you would have to cut into the sidewalls. We had a cabinet air on our 2000 Trailmanor, it was a great idea. All of this has to do with comfort and I just can't stand the noise and size of the roof air.
I will update this summer if this becomes reality.
