I just picked up my new truck yesterday after having the body sealed, and undercoat put on under the truck. While they had that done, I had the dealer put mud flaps on the front wheel, and floor mats. I get into the truck, the floor mat was slipping all over! I went back in, and mention this to the guy, and he said with those floor mats with the stuff plastic spikes it has nothing to grab onto vinyl floor (XL Cab). I asked what he would suggest to stop that, and he said you could do double sided tape, but I refuse to put tape on my floor! I came home, and I had a small rubber foam grip that is used in the kitchen drawer, and that didn't help much at all. What do you guys use for mat or keep them form slipping all over in your Ranger XL?
