Mine are return air vents (does NOT have a shut off or damper). I've had them installed on the Class C since 2006. During that time we were in the RV (full-time) in NC, GA, NC, FL, GA, FL, NC, TN, NC, NM, TX and now back in NM. While it doesn't rain much in NM, it did rain a lot while in Corpus Christi TX and let's face it, drought or no drought, it flat rains a lot in GA, NC, & TN. I mean honestly... there was emerald green MOSS growing in the window ledges of the skoolie when we left NC (it was brown by the time we hit the TX state line). Yes we have gotten tiny amounts of rain inside the openings. But less than if you walked in to the RV with wet feet from the rain. And I have driven in the rain (raining so hard we had to pull over, we couldn't see to drive). Driven on interstates with semi-trucks passing me. Not a problem. I figure you will probably get more water damage from accidentally leaving a window slightly open than you will from one of these vents. But I could be wrong... it's hot and I'm getting cranky.
