What is the bottom surface on the Mopar mats? Also, is the rear mat soft rubber or more like thin plastic? Does it match the fronts? If I recall the Husky X-Act from my F-150 they have cleats on the bottom - particularly the rear single piece. This makes them hard (and painful!) to place and remove. Also, while the fronts were nice and soft rubber, the rear was thinner and more plasticky. I get the feeling that the rear mat follows the the Husky Weather Beater line or something. I don’t think the company makes unique rear mats per product line, but a universal rear mat for both lines. The rear felt more like Weather Tech.
Edit - looking at the Husky FAQ, I am convinced the rear mat is always Weather Beater:
What is the difference between the WeatherBeater Floor Liners and X-act Contour Floor Liners?
Our X-act Contour Floor Liners and WeatherBeater Floor Liners are both custom molded to fit your vehicle exactly. The amount of floor coverage provided by the liner styles is very similar as well. The biggest difference is the material. The X-act Contour liners have a softer, more rubbery feel, whereas the WeatherBeaters are pliable, but not as rubbery. Both products offer superior protection.
