I have recently bought a 2011 Tahoe Q5i. No real problems except for the walk-thru windshield. There is not a way to keep it secured well when it is open. I boat on the intercoastal areas of North Carolina and the wind catches it and flips it closed. I have looked at getting some clamps to go on the top to clip it to the other windshield when it is open. I know I can bungy it as well, but just wondering what everyone else does.
