I have a Pace Edwards Full Metal Jacket roll type tonneau cover. Advantage is it can be locked about every 12". I can pull it back just in front of the hitch when towing the 5er to hide things in front of the hitch. Or all the way back over the hitch when not towing. Along with locking the tailgate it does provide some security for items in the bed. Disadvantages are it does take up some space at the front of the bed, and it does leak some at the tailgate since it just presses against it when closed.
No noise.
