I just picked up my Cabela's catalog and I see 2 great sets of floormats(albeit pricey @ $200+ a set), one by WeatherTech and the other by FOX ENT, so I call up to get a set for my Titan and neither makes a set for the Nissan.

. These are the only two I saw that are intelligently designed by extending onto the door threshold, preventing mud, snow and dirt almost completely from getting on the floor board.
Any of you guys out there know of a manufacturer that makes a decent set of floor mats for the truck that sees a lot of mud and dirt?
