I had an Extang Classic on my 1999 F-1500. I hated the snaps. Took a couple minutes to snap them all, and couldn't snap them all in the winter. My 2003 F-150 I got an AccessCover Limited rollup cover that used hook and loop design to attach cover to rails. I liked that cover much better. 20 seconds to roll or unroll and run my hand down the rails to attach. Almost full bed access when rolled up and should be in that same price range.
The Extang Full Tilt offers a snapless model which I would recommend over snaps if you stick with that model.
