Query: Pretty Nice Cover

Less heavy duty then the one that came from the dealer, but clearly a better design. It was very easy to install. The main problem with soft covers is that they get a lot tighter in cold weather. The factory cover did not address this problem at all. This Extang model deals with the problem in two ways, the snap buttons can be turned around so they are a little closer in, and also the ribs across the top can be moved to a lower slot. Smart people at Extang. The vinyl cover and the clamps look like very good quality. The rails look a bit flimsy, very light, but we'll see.There is one thing I definitely don't like. When you roll this up to the front, the roll up cover is held with 2 straps that join only with velcro. I liked the factory unit that had plastic snap together things like on a back pack. But this does seem to work.
