Thanks for the links streets, I only knew of the tonnues in the back of my summit and, they were listed as they were application specific. These links are more than adaquate to get me on the perfect truck bed protection, the only thing I won't go for is an old aluminum cap, mowhawks especially. I was thinking about rhino liner and getting the color custom matched but, a hard tonnue is a nice look and a little cheaper cause there paintable.
