Got a good deal on a BedRug on Amazon, but they sent the wrong model (for Classic body). I can return but won't get the same price again. Anybody happen know how different the new body style BedRug is and whether it's worth trying to install anyway? The bed looks very similar, but there are some differences in the cab wall indentation patterns, new indentations in the wheel wells, and a new curved shape in the tailgate corners.
