Randy I have to agree with slowmover, I think removing the A/C units is not in your best overall interest. Personally I think the humidity issue might be an issue if you lived in a humid region, but more importantly how about the comfort of the people in the RV?
Is gaining a couple of tenths mpg worth not having some A/C when you finally find the time to go visit somewhere interesting and relax? Unless you plan on relocating them in the basement compartments like some of the Prevost converters do, I'd say that's a bad idea compared to building some fairings to cut the drag as much as possible.
On the other hand, as they say in Oklahoma, it ain't none of my business so never mind.
