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? Should I go with the fancy rain sensing models that automatically close, or put vent covers over the fans on the outside? Or both?

The old fifth in the signature just had a bedroom vent, and waking up with a wet spot on the bed when it rained overnight was not at the top of my fun list.

    WAY overkill, IMHO.
    And just something else to go wrong.

    Cover the vents if you must but just leaving them only half way open should protect against a surprise shower.
  • Personally I see no logic whatsoever to a vent that automatically opens and closes :h ... install a vent cover and leave the vent open 24/7, closing it only when you may be running A/C 24/7 in extremely hot weather. I likewise see no need for temp sensing either - just leave the darned vent open. ;)
