Observations from the road, stuff that really works...

Thanks for sharing, much appreciated.

Will definitely keep the Maxx Air Turbo in mind. Not cheap but the reviews look good. On the other hand, not that much more expensive than the "automatic" close-on-rain vents and much more reliable.

So many things to go wrong on the "automatic" vents: rain detector fails, drive motor fails, drive train locks up, battery goes dead. The Maxx Air has no moving parts thus "inherently safe".
