Morrie and I have been talking for months about products for my bed. He recommended that I wait for an "updated Roll-X with a new locking mechanism" coming out in August. He told me he would give me specifics on the updates after it arrived, but it was easy to figure out the updates after I had installed it yesterday. I couldn't find anywhere that listed the updates, so I thought I would post them up. I made a video that reviews the cover and its updates here. If you prefer a list version, the updates to the updated Roll-X are as follows: 4 bolts (2 bolts on each rail) attach the cover to the rails, instead of the single hand-tightened plastic fastener for each side. The locking actuator is now a flat top bolt with a wing nut. It allows you to adjust the height of the locking mechanism. The weather stripping that was attached to the back of the cover has been relocated to the interior of the cover. This allows you to close the tailgate with the cover closed, but does not seal out water as well. These were the updates that I noticed, there may be more but I did not have an older Roll-X to compare it to.
