 I have a 2016 Duramax, and the Chevy's have the threaded nutserts already installed to accept the brackets. Just look behind the tire at 10 oclock and two oclock. The factory setup is for Curt rails and brackets. They are very stout. If you buy them on Amazon you get the best price. The Curt system is a standard setup that will accept many different hitch's. Here are the brackets. Good luck with it.
Do all 2016 Duramax equipped trucks have this? Can you please share a pic? I don't think mine does.
I believe all three heavy duty trucks are equipped this way.  Buy a custom rail mount kit and the only drilling you'll need to do is through the bed floor.  My Ram was this way also.  I got mine off etrailer.
