I spent hours on-line and talking to a dealer or two trying to decide which cover to buy for our 2008 F250 Super Duty. After reading lots of blogs and reviews I decided on the Extang Express. I just installed it and so far I couldn't be happier with my decision. The engineering and manufacturing of the hardware is outstanding. Everything fits precisely the way it should and it was so easy to install I was embarrassed to think that I almost paid a dealer $75 to install it. I'm no handy man and it took less than 30 minutes to install it. The diagrams in the install guide could be a little better but one look at the hardware and it was obvious how it went together.With the great warranty and feedback I've read about the company I believe I'll be happy with this product for the long haul.
