Even without the cover the rain sensor is dang near worthless.

I disagree. I have Fantastic Vent's 6600R in my bathroom - with no vent cover over it. It is about 10 inches from the edge of the roof on the driver's side. I was hanging out with a friend parked in the site next to me - on my driver's side. We were under his awning during a heavy afternoon drizzle and one of the afternoon's highlights was watching the stupid vent close and reopen every 20 minutes. The rain sensor on my 6600R works perfectly.
