Marty,

The bows are straight and therefore do not stick up above the frame rail line. The whole cover sits above the truck bed sides by about an inch.

I looked at the Access cover at the local shop when I bought my Truxedo. Very similar and both were the same price there.
The differences were:

- The guy at the shop told me the Truxedo seals on all four sides and the Access did not (I am not sure why, unless the Access does not seal against the tailgate)

- The Access could be opened with a hidden button without lowering the tailgate, but I think you can remove the button to take advantage of the locking tailgate.

- The frame rails on the Access (where it velcros) slope, top towards the center of the bed. The Truxedo velcro rails sit vertically.

I just thought the Truxedo looked sharper.
