Chum Lee,

There is, or was, a commercially available evaporatetive cooler designed for use in an RV. However, it was about the same price as a regular roof top unit.

Hi Don: IMO, there's no reason why you couldn't put an evaporative cooling system on any MH. They WORK. BUT only in hot dry climates (0-20% relative humidity) where you have a readily available supply of fresh water. (like 10 gallons per day) In my Class A MH with an 80 gallon fresh water tank, that simply doesn't work. (especially while boondocking in the deserts SW) Now if I'm staying in an RV park with full hookups, I just use the regular rooftop AC unit which works fine. I'm not interested in adding the complexity of an evaporative cooling system to an HVAC system that already works fine without it. IMO, excessive moisture inside a motorhome is always a bad idea. If you look at the RV industry, in general, they seem to agree with me. (well more accurately, ego set aside, I agree with them)

I've been designing/building things for over 50 years now. Evaporative cooling systems are an economical solution and definitely have their place. IMO, a motorhome is NOT one of them.
