We had basement air in our pusher which was equivalant to 2 15k units. It was great if the temps wher 85 and under, above that it did not keep up. It was ineffiecient to run the air from the back bottom side of the rig all the way to say the front. Also the cooling fins need to be loated at the side of the rv, so this takes up storage and looks like crap and the unit gets trashed by road spray. It is much more quiet, but to many downsides, I think the roof top units are two easy and inexpensive for mfg's to much much effort to solving the issues with basement air.
BTW we made some changes in the floorplan, next week when I have have internet I will post them.
