Have a 2020 GMC Sierra 3500 on order. This will be the first Dmax I’ve had, only ever owned the Cummins. I’ve been in the market for a new truck for a while and after a decent bit of research I decided I would try out the Duramax/Allison combo. Hope to learn as much about these trucks as possible. Thanks for having me!

Welcome. I'm sure you will love it. There are a few threads here that may be worth reading that cover this new platform. Help you get up to speed on its quarks and issues. And the good things too
