Picking up my new 2024 GMC 3500HD Denali Duramax - Real World MPG w/ 10 Speed Allison Transmission

So how is the new 2024 GMC 3500 HD Denali Duramax with the 10 Speed Allison transmission on fuel? This is real-world MPG while still in the break-in period. As many of you know, the MPG keeps getting better as the motor breaks in.

What are your thoughts on the new truck? Questions? Let me know in the comments below. Will be seeing a lot of this truck over on 221B Tactical.
