I have the Weathertech's and they are great for keeping the truck clean and they fit and look nice. Having said that, they are stiff and only connected with three screws going into plastic inserts in the fenders. If you plan to go over big obstacles, should they catch, they will certainly break off and tear out the inserts. If you plan to do that stuff I would get the floppy rubber ones, but I was amazed at how much they charge for those. I don't plan to go over waterfall shelf or boulder obstacles so I have not installed the RCI rock sliders either. For that I suppose you should be driving a Jeep anyway.
