I think the d-series would look better with a bed liner if a mod were made that would be cool but i think if someone could make a paint job with a good bed liner that would be easier, just an idea.
Sorry to beat a dead horse, but if scratches are ever implemented, the bedliner could prevent scratches in the bed of a truck, like what it does in real life. Would be useful for loading boxes, crates and just random crap into the truck and keeping it looking nice!
