I would like to leave a vent open, but my wife doesn't believe it won't fly off. If I convinced her it wouldn't and it did, you can imagine the rest. Yes, I could get FF to replace it, but what do we do in the meantime? Aluminum tape I suppose, if the tape stays on. Plus I would have to climb up on the roof and I hate it up there (I am not a height friendly person). My wife won't climb up there even though she would do better than I up on top (and getting down is the worse part).
Cars have had flow through ventilation for decades and from what I read above, it appears that at least the Eddie Bauer model does too. Of course, car companies provided screens. Any other models have that?
