[QUOTE=padlin00;673901]I don't understand the open window thing.
All I can tell you it works for me. The "theory" is, the RV changes conditions with the weather. If it's real cold at night then warms up in the day time and the RV is shut up tight and cant "breathe", then you're going to have condensation and THAT'S where the mildew and mold can start.
I keep my
Scamp under its own carport thus preventing it from heating up in the sun during the winter (AND summer) as much so the temps inside wont fluctuate as bad.
I dont go in my Scamp during the winter and see condensation on the windows. Of course if I turn on some heavy heat, YES. But I still leave the windows and vent cracked open...even with heat. (But it's rare- I do not camp in the winter). Anyway, with the windows and vents open, my Scamp is continually "breathing".
SO, you'll have to go to Brother Google and see if he can explain it better. But that's my story and I'm a stickin to it.
