..... people have had trouble seeing out of the back windows when tinted darker
I put 5% limo tint on all windows behind the front doors. Problem seeing out.... ohh heck yes, big time! The 5% tint plus the factory tint takes visibility down to about 1%. But I learned to drive with door mounted rear view mirrors rather quickly with my Excursion. Plus the Tahoe has the rear view camera whenever I do go backwards in it. I don't view not being able to see out the back windows as a problem when I want the dark tint for privacy.
