Bedrug Vanrug
The Bedrug Vanrug is a great product; I had one in the Ford TC I recently traded for my PM. Easy on the knees, keeps cargo from sliding, and cleans up with a vac. Still looked like new after 2 years, but I wasn't hauling greasy or muddy stuff. Ordered one for the new PM and hope to install it soon.
Note Bedrug is the brand and Vanrug is the mat with the carpeted face that is the subject of this thread. Bedrug also sells a hard-plastic faced mat named Vantred but I found that to be too slippery and cargo slid around. Vantred would probably fare better than Vanrug on the greasy and muddy stuff though.
Lastly, I also found it very difficult to find any discounts on Bedrug products; retailers seem to exclude their products from promotions. However after some research I bought mine from AutoAnything, who applied a small discount to the order when I expressed my disappointment their promo code did not work.
