by vented do you mean with a gap between the visor and the roof, I was thinking after seeing them like that on most trucks that I would have to do that as well to allow the air out so it would not blow off, If attached directly to the roof as in my mock up( wish I could figure out the pictures would save 1000 words) I was worried that I would be trapping air and even though it is a steep angle the air would run up the windshield and stop putting a lot of pressure on the visor acting like a scoop eliminating the possible advantages of the deflector
