Great cover - but doesn't roll smoothly

Reviewed By Jeff S (Seattle, WA) Reviewed for a 2012 GMC Sierra —6/2/2016 11:45 AM

Installation was fairly straightforward. Took about an hour to complete. For the first few days, it rolled smoothly - but then, after getting dirty, it now stops often as it gets to within 6 inches or so of the box. I have to pull it back, and then push it hard to get it to roll all the way into the box.
