THe following is my experience on the "Pace Edwards" I have one on my 99 super crew. I bought my truck used with 5000k and it came with the cover. All I can say is I'm damn glad I didn't pay for it (so to speak)!!!! As soon as I have the money to buy another (snap) cover, I'm taking this Piece of S**t off!!!! They don't hold up for crap, especially if your opening and closing them a lot. I constantly have to adjust mine. The plastic housing that holds it is warped and the vinyl cover is fading badly. I'm also on my 4th lock. They are a great idea but they are not very durable! Just thought you'd like to know! There are other manufactures that make roll tops and maybe they are better. I couldn’t tell ya. But I can tell ya the Pace Edwards are NOT worth the money!
