I absolutely love my Line-X. I did a lot of research before deciding on it (including searching FTE, there's lots of info here) and no-one had a bad thing to say about it. My truck had a drop in liner and with a former 5th wheel & propane conversion (both removed) it had 84 holes of various sizes in the box, which the Line-X covers up beautifully. I use my truck for lots of hauling and the Line-X stands up good to gravel, shovel work, etc.

Line X is great. Just check out the 04-06 F150 area....A guy had a battery tip over and acid went all over the place....The bedliner isnt damaged...but the concrete was alittle shiney after it was all said and done
