On my last 2 trucks I've had Rhino Lining. Loved it in the 1st truck. Bought it before we got the 5er, & had a camper shell on the bed. I loved it, nothing slid around in the back & the bed was protected. Had Rhino Lining put on our current truck, purchaced after the 5er. They now have 2 levels of Rhino Lining. The "old" type is thick & sort of rubbery, that's what I've got & had on the last truck. The "new" type is thinner & seems more like the LineX lining, but seems a bit more rubbery, and I think would at least slow down the sliding of stuff in the bed. I was told the "new" type of Rhino Lining was more of an industrial type of lining. I'm kind of wishing that I'd have let the dealer put the "new" type of lining on the new truck, because in the time we've had the truck (it's a 2011) there are a few "chips" in the lining, where something has gouged out some small holes in the lining that I'm going to have to get fixed.
