I had a fantastic fan with thermostat and an aero-flo cover in my last trailer. The fan was quiet and worked well but the cover was hard to keep clean.
The new max-fan is interesting http://is.gd/5yaej but would probably not work as well as a fixed cover in snowy conditions.
The max-air II looks like it has the most open area...Any suggestions for covers and other fans appreciated.
