Hey all. Just bought the Mrs. a 2023 xt6 Premium Luxury. Opulent blue/cirrus interior. Sadly, didn’t have the smart tow package installed, but figure I can retrofit it. Looking at a draw-tite class III hitch w/ 7 pin connector. Can swap out the alternator easily enough, but does anyone know just what’s included with the “heavy-duty cooling system”? Is it just a beefier radiator? Hard to do the research right now as even the online wholesalers aren’t listing anything but accessories yet. Thanks!
