99 degree boondocking

[Jon in AZ]

Evaporative cooling only works in low relative humidity. Completely useless in the eastern 2/3 of the continent. Even in AZ it’s not much use during the muggy monsoon season (July-August). I had it in a 27’ trailer I lived in full-time for four years. It increases indoor humidity, and no matter how often you clean the thing and change the pads, it always seems to have a funky damp smell.

Even under the right conditions, I’d be surprised if a small 12V unit could move enough air and water to cool even a small trailer.

Thanks Jon. Without a/c in our 13ft Scamp we thought it was worth a shot. We may have to wait until we visit the dry Southwest to give our Mighty Kool a fair test.
