Does anyone use one?We are removing our roof AC due to the fact we never use it. In fact we have never used it once. Sure there were times that we were hot but using the air means running the genset which we also never do. Too noisy, uses up propane etc. Recently my father passed and while settling his estate we used his evap cooler and found it to be superior to AC in that it was a nice moist cool which countered the dry heat in Reno.We are considering replacing the roof AC with fantastic fan or... ThisAnyone use one?Initial pros and cons that come to mind:Pro:Light and simple.Very energy efficient does not need a generatorAdds moisture to dry airCons:Requires arid conditions. Works poorly/not at all in humid climate.Pretty expensive for what it isRequires pumping water into reservoir on the roof (what could go wrong?) :SAnyone with experience with one of these?Thanks, Greg

We have always use these (we call them swamp coolers) on our house here in the desert and yes, they are only good with very low humidity. Typically, the water pans are leak proof, but if I had one on my rv, I would definitely make some sort of drain that I could access easily for when we would travel. A simple 1/4 or 1/2 horse AC motor is somewhat efficient, but you also need a small water pump.Another con is that they are not small and would add sufficient height to the top of the rv and would present a large wind drag, so securing it to the top could be difficult.The worse con is.... boy these things are really, really ugly.Ron

Thanks for your input. I didn't measure to compare but I thought that it looked ok as far as profile to my stock AC unit.

I used one long time ago and still have it in my storage "just in case I would like it again"The biggest advantage is low power consumption on 12V, so no genset necessary. But they are higher maintenance than AC. If you leave water in them off season, you will find mildew next spring. When they might work for some, I don't think they are worth $500

I attached an aero cool to the side vent door on our fifthwheel. I made a boot out of bubble foil to connect the cooler. Best mod, kept us comfy in the desert heat. 115 outside, 65 inside on low, with every window open and the door. It saved our lives, and made life so much more enjoyable. We could sleep at night, the humm from the fan I miss alot. We would open the fantastic fan above our bed and turn it on low, it would drag the cool air into the master bed room.But...I was able to install ours on the side of our rig, on blocks. I would never install it on the roof, if I traveled with it. The high profile will cause it to loosen up and fall off your rig.Buy a small swamp cooler, and rig up a way to put it in a window. That way you can handle it easier. A swamp cooler in a hot,dry climate is perfect. They use alot of water tho.

You will not be comfortable in Florida with it.
