These weather Tech mats are the worst product ever. They do not fit my 2020 GMC Sierra 1500 properly, they have been curled since the day they arrive and I have done everything to straighten them out.
About 4 months ago the cabin of my truck developed a very bad stink that no one could identify. It was a cross between a mold, mildew, rotten leaf odor. I did everything possible spending over $300 on products to eliminate the smell. It wasn't until I bought auto mold foggers for my truck that I discovered it was these Weather Tech mats, and only because I left them out overnight, put them in my garage and the next morning my garage had the same smell. It took four months but my truck doesn't smell bad any longer. I hope this helps some one else.
