We have had 2 Shur Flo fans for about 4 years now in our fiver - one in the living room and one in the bedroom.
We were fulltiming and did a lot of dry camping and they really came in handy.
Some nights it was just warm enuf to turn on the fans and if dry camping we had no a/c running.
They work awesome, are reversible and are very quite!
