Purchased my cover in 2009 and have installed on two General Motors pickup trucks without complication. After traveling over a total 100,000 miles the cover still functions like new. I replaced a roll-top tourneau cover with the Peragon product. It is much stronger and more durable. Has less vibration and noise at highway speeds, and has not faded in the southwest desert sun unlike my original roll-top cover. I would highly recommend this product to all new users!
