I can't seem to get a solid answer on my max towing capacity as well as the weight of my car. There is "a range" from 3500 to 7200 on the tow capacity. ( pretty big discrepancy) It seems the 2019 and newer can tow more than the 2018? I have called multiple Jeep dealers, even with my Vin number, and can't get a firm answer. Help!
