I have the Bed Rug that covers the bed and tailgate, not the sides of the bed. It fits well does a great job of protecting the bed and keeping things from sliding around.
This is what I have and honestly I love it. It's weird, because you can slide stuff into the bed a lot easier than with just the spray on bedliner, but once you put something in it doesn't slide around like on the bedliner.
I thought about getting the whole thing, but I didn't want to be bothered by all the Velcro.
Anyway, it is definitely worth the money. It seems like a lot for some foam and waterproof polypropylene, but it is an instant fit and looks really nice.
Edit: I don't have the tailgate part. I didn't want to be bothered with the Velcro so I just got the bed. But I have a truck cap so I don't need the Velcro.
