Well, I have had my Linex cover installed for about a week now. I am more than happy with it. The price and look are great IMHO. I need to tighten up the front as I have bed caps and the front lip has a small gap that needs to be sealed better. A mere tightening down of the front latch support should work. Another option would be to get rid of the rails (always wanted to) but was worried about what the underside looks like once the rails come off. I imagine it is only 3M tape holding that on. Disregard the date, my daughter's camera was set up incorrectly! I guess my feedback for Linex will be to increase the size of their front rail seal by about 1/4" to accomodate the bed rail option. I imagine there will be a little tweaking here and there from LineX as mine is only the 52nd off the production line. However, even with the gap I only had a small bead of water in there after some last weeks storms cells moved through the area.
