I recently purchased a 2011 Chevy Z71 and the bed cover was on it. The dealer didn't give me any instructions so to speak so I got on Peragon web site. With in a few minutes I had it figured out. This cover is simply the berries if you will. It is easy to use folds up nicely and if you need few more inches it removes easily and is easy to replace. I was missing an end plug called Peragon. Rodger answered with an enthusiastic tone a voice and is sending me a pair at no charge. Thank you Rodger for the great customer service. My truck is black and the cover really adds to the appearance of the truck. If I replace this unit I would do it with another Peragon. I highly recommend it to acquaintances and friends when they see it.
