The weathertech mats cover a _LOT_ more area than the OEM mats. I posted pictures of the difference on another thread somewhere. The difference is startling to say the least.

As others have stated, the weathetech mats are a little "slippery". Most of the time it is not an issue. However, one time when I took the truck through a "full service car wash", they applied armor all to the mats, and it was so slippery it was like a sheet of ice under my feet...

 

Thanks for the response. I'm definitely going to get something to replace the OEM mats.
