Wait... What?

I'm just curious why we are so bent on selling trucks based on what NOT to do with them. Yes, people abuse all sorts of stuff, but is that really a selling point? I've had Duraliner slide in bed liners in two trucks now and I'm completely satisfied with their performance. I doubt concrete blocks would make an appreciable dent if I were so silly as to dump them in there like that, aluminum or steel bed. A little sanity in marketing would be nice.
