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 have that fan on mine and have never liked it. Mine makes far more noise for the amount of air moved than the Fantastic Vent fan or the Vortex fan.

thermostat seems to just control the fan not the lid.
I agree I would prefer the lid should close if the fan is off.

Thanks for posting that picture.
The had to be quieter with the fan motor mounted where it is.
I sure wish I could find one fore sale, new or used.
I wonder why they are no longer manufactured?

Have FF with rain sensors. Installed vent covers so that I can run fans when it is raining.

With the fan on the outer edge, it looks like it would be quiet.

We have the Fantastic vents with rain sensors. I have gotten to the point where I have pulled the fuses out of them because they keep opening and turning themselves on even when the thermostats are turned off. I am giving serious consideration to buying new manual vents and getting vent covers.

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.

Had a vent cover. It went away when I installed the FF with rain sensor.
Works for me in the bathroom. Bedroom vent never opens.

On edit:
I do miss the remote to allow those that cannot reach to be able to run the fan.

Vent covers are the way I'd go.

[Jayco-noslide]

We love the fantastic fan over our bed and it has a good cover so I never use the temp setting or the rain sensor.

I would go with the vent covers. One plus is if you ever crack one of your existing vents and don't know it, if you have the add-on vent cover like a Maxx Air, etc, your rig won't get flooded if it rains. Vent covers also crack by themselves from sun exposure eventually, btw.

I always take the simplest route. A cover has no moving parts, uses no power, uses no sensors, and thus is a lot less likely to fail.
