Floor Mats for a '11 Sport rubber floor
 

I just purchased a really nice 2011 Silver Ext Cab Sport 4X4. It has the rubber floor. Are there any forum recommended floor mats for this floor? I would kinda like to keep the truck nice. Please advise.

weather tech mats are the best you can buy a little pricey but well worth money

The vinyl floor yours has is very easy to keep clean. A wipe with a damp cloth is usually sufficient to clean the surface with normal use. Floor mats in general, unless the back side is very tacky, will slide on the slick-ish floor without some help adhering. Quite the hazard for a driver.

Even if you did get into something particularly unsavory, your favorite cleaner (simple green for example) and an old toothbrush would cut through it very easily.

Unless you can find a set of mats that will not slip or slide, I would advise against mats on that type of floor just for that reason alone.
