I have a 2021 GMC Sierra 2500 AT4 that doesn't have the gooseneck/5th wheel prep package. I was wondering if anyone knows if it's possible to install a puck system into the truck anyway. I'm not a fan of the aftermarket gooseneck hitches, and prefer having the pucks. GM said it has to be done by the manufacturer, but I thought I'd take a chance to see if anyone has a different opinion.
