new fan - vent cover or rain sensor?

[Flapper]

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.

I can just talk about what we have, so we have a thermostat controlled Fantastic Fan, with just a standard vent cover over it. We open and close the fan cover manually, but usually it just stays open. No rain sensor, because we didn't think it would work under the vent hood, as no rain ever gets to it. In our case, it is used to insure heat removal from the coach if power goes off, or when at home, just to keep it fromgetting too hot inside. We have had ours for many years, I think there are better options available now.

Get the MaxxAir. It comes with a built in cover. It is less expensive than the Fan-tastic and is easier to install, meaning there is no secondary install of an additional cover. I love mine.

Vent cover.

I am also looking at the fan-tastic vent. Does anyone know the amp draw for the basic 1250 model?

I have two Fantastic Fans with covers on both - one with the rain sensor. All the rain sensors do is keep you awake at night if it is raining as they open and close the lid! :E

Put a cover over the fan and you can run it during the rain and the lid will last forever. Mine are 13 years old and still look like new.

My covers lets me run the fans when it's raining. I bought mine because it had a remote control and 13 speeds, not for the rain sensor. Having a cover on them is insurance and not relying on just the lid. The lid will probably last longer because it's not in direct sunlight. As far as getting smacked by a tree climb etc, the cover may be thicker and more forgiving than a lid.

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. 😉
