dang.

I tried a swamp cooler in my RV when 1 of the A/C units failed and the results were quite obvious. If you stood right in front of the air outlet it felt pretty good. However, it did absolutely nothing to actually cool the interior of the RV. We then bought a "real" portable A/C unit with an exhaust hose that must be run out the window. THAT WORKS! However, it generates a whole lot of water which you must deal with on a frequent basis or have an option allowing a continuous drain of the water condensation. Luckily, we were able to run a hose from the A/C unit to a drain and it could run 24 hours without attention. If not, the water needed to be drained every couple of hours to prevent over-flow.

The best way to determine if a evaporative cooler (the correct term) will work is to check the outside dew point. Under 50 degrees the cooler will work with lower being better. Above 50 degrees, forget it.

Im going to try making a homemade swamp cooler. Probably do the 5 gallon bucket method you can find all over youtube. But instead of a desk fan will use a 4" blower.
