new fan - vent cover or rain sensor?
Picking up my new Grand Design TT (2670MK) next week. It has cheap fans in the living room and bedroom. Will be going to Fan-tastic or MaxxAir on both. Temp. sensing is a must. But what about rain...

I can't comment on the other options, but I have vent covers (Max Air) and Vortex fans. Last winter I accidentally left the roof vents open all winter. No rain nor snow got in even under pretty severe conditions. I can't complain about that.
