I recently purchased a 2011 Chevy Z71. It had a Peragon bed cover. The cover had a great appearance and was part of what drew my eye to the vehicle. The dealer didn't give me any instructions on how to use it. I went to Peragon.com and with in a few minutes I was using it. What a great idea. If you need a little more room it is easy to remove and reinstall. If I wear it out I would purchase another. I have no problem recommending Peragon to others and have.
Service is also great. I lost a rail cap from the back. I called Peragon and spoke with Rodger. He was professional and was quick to help me. Also sent the replacement caps at no charge. Great customer service and product.
