I dark tinted every window in the coach except for the windshield and I also did the 24" dark tinted visor on that! The visor is incredible! I will say that backing into my building during the daylight hours it is harder to see in the mirrors but, for every other reason....Dark tint is the best!
I have been in alot of states with the coach and have yet to have a problem with the cops. I think if you get pulled for another reason they may bring it up.
I also have the drop shade for the driver seat and it too is the bomb!
I highly suggest a professional tinter and a quality product like Lumar for the tint.
