Sheridan, I think that visor looks awesome on your suburban (even with a different patina than the truck).
It's too bad not being able to open the windshield is a deal breaker for you. Could you not fab up something so that you're able to? It seems like only the center mount would be in the way of opening the windshield?
I too think it looks cool and may think harder about how I could fabricate a center support bracket that is adjustable. Maybe it is time to put that engineering degree to use in developing something. I LOVE driving it with the windshield open and would not give that up.
