I'm a believer in tinted windows too. I think the UV protection helps things like dashboards and interiors from deterioration. And in general last longer. Not to mention, I don't feel like I'm driving around in a fishbowl with tinted windows. I have a 07 Classic 1500 Z71 and my 07 LBZ. I don't have a garage and trees are on wrong side of my FL house to park under. No cracks or rattles in either truck. Between the 2, I've got almost 425,000 miles.
