I noticed my Tundra’s floor mats are always askew and as a result all those in and out in muddy, wet boots have taken a toll that no vacuuming, cleaning are going to remove at this point. I am not an overly fastidious vehicle owner, but maybe a little preventive maintenance wouldn’t hurt. Getting in the rig with muddy boots and wet waders do eventually take the edge off the interior. The exterior has enough character blemishes too. So, perhaps the floor mats with upraised edges might catch more snow, water, mud, dust and gravel? Here is a comparison of the two leading, collect the crap, floor mats (I don’t have either one, so no dog in the fight): Husky v. Weather Tech
