X2, both swivel seats on 2017. Looked into seat covers, still undecided. Anther OP suggested Rocky Mountain Sheepskins, out of San Jose, Ca. Also taking a look at Coverking, which does a retail website and also via Costco at reduced pricing. Have used them and their neoprene covers, on two of my pickups, and they fit and wear well. As for floor mats, take a look at these:

Not as heavy duty as Weathertec, but still does an excellent job. Plus, fits well over top of existing factory carpet and adds to keeping road noise down. Took about a week to get them. Customer service was very good, too.
