Pretty sure there are bolt-on tow kits for the Crew Cab S out there but make sure you find one that's built tough and fits snug. Reese and Curt got some options for you. Good luck.Got a 2019 Crew Cab S and Im looking to add a tow package that bolts onto the frame. Wondering if anyone's done this mod already and can recommend a good setup that fits decently. Thanks..
