Winnebago basement air
I have searched and read as much as I can about this. I understand that it takes away outside storage. But, does it work any better that two air conditioners mounted on the roof? Does it really coo...

From what I under stand ,when the EPA made diesels add the DEF. This took the space of the basement air. From what I know Winnebago was the only one that had basement air. Unless the
high dollar ones did. One thing I do know is , the roof air is noise. Have been up on the roof of my 13 Winnebago 40U many times. Replaced the exhaust blades twice. The c & d model blades quieted the out side noise but the inside ,not so much.
Just for comparison, some Prevost coaches have basement air called 'Cruise-Airs'. They also offer OTR (over-the-road-air) that cools the whole coach only when the engine is running going down the road. The Cruise Airs are basement installed and are also heat-pumps. People have complained about the exterior noise that they make around the patio. Some of these coaches will have two Cruise Airs and two roof airs or maybe 4 Cruise Airs and no roof air units. A common place for one is behind the front bumper.
Four slide coaches, like ours, cannot have Cruise-Airs or OTA as the slide mechanisms interfere with the venting needed. So, we have four roof airs where the venting is designed by a CAD system to accommodate the smoothest flow of air (quiet) with no hard bends or 90 degree turns. It's amazing the flow of air compared to the 'lack' of noise (although there is some noise).
Because of the wall insulation, our converter uses four low-profile 13,500 btu rooftop units. Generally, three are plenty to keep the coach cool. If it is heat-soaked, all four will be needed to get the interior cooled down. The problem is the breaker at the pole, if it's old, we might throw a breaker (which has happened).
99% of the time, I will run two airs going down the road along with the front dash air and aux. air (for the co-pilot). That way, we are not heat-soaked once we arrive at our destination. At night, once the coach is comfortable, I will turn off the bedroom air for the 'quiet' time and leave whatever other airs needed to maintain temp.
Our DEF tank is 16 gallons so it's larger than some but not huge where it would take up an enormous amount of space.
Safe travels,
