I have a Bedrug in my Tacoma. Opted for the full setup so the entire bed is carpeted including the interior walls and tailgate.

It is really, really nice. Not only is it easy on my aging knees but it prevents "truck rash", my tools and cargo no longer get all scraped up from sliding around. It is easy to clean and seems to be impervious to pretty much everything except velcro. Yes, velcro. Keep that stuff away from it or it will pull the fibers out of the rug.

That said, my truck has a camper shell/topper on it so the rug is out of the elements. The company claims they are good to go in open bed trucks but I cannot vouch for it.
