You learn something everyday! I was unaware of those factory flap vent things, but something like that could be just what I need (and it saves me having to fab stuff up). As for air under the cab being hot and potentially having some fumes in it, remember that what I am after is an air exit, not an intake. The cowl vent on the Fargolet scoops an obscene amount of fresh, cool air into the cab, but that air needs an escape. I can roll down a window a bit, but the resulting noise is pretty bad. For me, the most convenient place would be under the seat as it is far from my ears, I would not have to cut a hole into the rear of the cab, and I would not have to remove and modify the interior panel. Air does however do funny things, so the suggestion about running a test with the battery cover removed is a smart idea. Of course I did a wonderful job of sealing it, and then covering it in sound deadener as I knew with absolute certainty that I would never have to use it!!!!

Thanks guys!
