After 3 years of install on the WeatherTech I have to agree with you. The front fit great and the rear one-piece did originally. The edges near the storage bins has curled up and no longer sits flat. The center that goes over the hump slides left and right giving it a loose feel. I do have three sitting across the back regularly so wear and tear is probably higher than most.I have a 2016 RAM 1500 Laramie LongHorn. Just a word of caution, if you have the rear floor storage compartments, the weathertech one piece floor mat is worthless, will not stay put and slides around on the floor when you get in and out of the truck, I even tried to add Velcro pieces to secure it would not stay put. I consider it a slip hazard and removed it. The front floor mats are great.
Absolutely love my WeatherTech digital fit liners. Have been running them in all my vehicles for probably around a decade now. However, I do have to agree, they can be a bit slippery when wet. I can recall a few foot slips when stepping in my truck.Now if they were made of a softer "rubbery" material they would have something.
If your shoes are wet or have a little snow under them you better be hanging on to something when you swing up into your seat.
My foot slipped out from under me and had I not been hanging on to the handle I would have fallen backwards and onto the ground. :smiledown:
I dumped them in the trash can after that. I bought a "rubbery" mat at K-Mart that works just fine. :smileup:
