yes, they did tell me not to put anything over 50 lbs in the bed for 24 hrs, but it was well worth the negligible wait.
Then I noticed that a truck parked next door to my work had a Line-X liner so I had the opportunity to compare them side by side. I have to say, the Rhino liner far exceeds the looks of the Line-X due to the way they bevel the edges, and the Rhino has a meaner, more rugged look to it and also looks like it's thicker. Comparatively, I'd say the Line-X looked more like a plastic drop-in liner. Anyway, besides looks, I had done what you're doing now - researching on the net - and came up with Rhino and am very happy.
