Peragon Cover
The rails that the wheels/rollers fit into are not completely tight. There is a little bit of play or movement that is required to make it all function correctly. You will notice in the rear view mirror when it is windy or if you are doing 80+mph as we are allowed to down here (tollways are 80mph and 85mph speed limits) that the panels will have a little movement to them at times, but nothing substantial. You can't hear it or notice it from inside the truck at all. If you have the rear slider open, there are times when you hear it slightly, but not anything overbearing.

Had one on my 2011 for 4 years with no problems, I kept the tracks well greased and worked flawless every time. I did have it at a car wash one time and noticed the panels flex a good 4 inches from the dryers blower, those blowers are powerful! Would love to get one for the new truck.
