I've had Rhino, Line-X, and others and at the end of the day, it's like everyoe else, who does the prep and installation makes the difference. There's Rhino guy here that does the most incredible job I've seen to date, and I always go with him now, but I'm sure there are other guys with other brands who do just as good. I don't think there's any advanatge to any of their products. My advice would be to look at some (several) of the beds that particular shop has done and go from there. A quality guy will remove all the hardware (nuts, bols, tie doens etc) in the bed, put the liner in and then replace the hardware. Some just apply the liner over the bolts, etc and that looks like shit.
