I dont wanna rain on your parade, BUT, even with mud flaps, you`ll still get crap on the doors no matter what. Nature of the beast... the fenders and the body panels stick out and catch everything. The tires even stick out a ways on these 4th gen trucks and flings everything down the sides of the truck body. I have the husky brand mud flaps and are a touch wider than the weather tech flaps, and they STILL let the crap fly up onto my truck. I`m not sayin it wont help some, but dont get to excited and think it will do much in keeping your truck clean either. The flap`s will only protect a little tiny part of the front and rear fenders. Seal them up with silicone when you install them, that will keep the sh!t from seaping behind them. After i installed mine, i then sealed all the way around the outer edge of the flaps as well. I even covered the screws with silicone so as to keep them from rusting like my last truck did. I also went completely around the wheel wells with silicone so nothing could get into that area either.
