Welcome to buying a freshly re-designed platform! Went through some of that myself when I bought mine a few years ago, except I got lucky and the frame was the same from the 14 to the 15, only the body changed.
Do you have the factory installed puck system? I think Curt makes a package that fits. I donít know if they have released one for the 2020 yet, but surely GM can tell you where to get a hold of one.
