Try trailering it backed on your trailer. I know you shouldn't have to do that, but it will probably solve the problem. I started doing it because I didn't like the front of the roof overhang flopping. It's not just a polaris thing, I've had that same issue with a Teryx4 and Mule Pro
You might want to start trailering it backed on your trailer like I do. I started doing that because of the wind causing the front of the roof to flop and to protect that $1500 windshield. Or you can get a padded windshield cover from Pro Fab outdoors like I have for my Ranger
