At my dealership we have tried rhino lining, line-x, and lynntrucks. As far as we have seen the line-X Holds up the best after a couple of years. I would go with them if it were me. Also keep in mind the dealership only pays 325.00 for long bed over the rail. You should be able to get it done for about 400.00 cash. or less.I've been looking at both Rhino and Line-X bed liners. So far I'm liking Line-xs looks and feel better...any suggestions? is there a third spray-in bed liner company thats starts with a "v" or something?
