That's odd you say that about the Extang, as members here typically have good things to say about them. I had the Extang Revolution, the model that is level with the bed rails, but then switched it out for the Truxedo that sits on top of bed rails (I needed the extra height to fit a camping gear box in the bed and would still be able to cover). The Extang fit like a glove and I liked the fact that it did not have velcro or snaps to hold it down. I also like my Truxedo as it fits great and has held up well over time.
