My monthly Onstar report lists mine as an AT4 Denali if that helps?

What do you expect to be different from a Denali except for badging, colors and stitching?

Dealer told me about several subtle differences. I think he made a few of these up; like the AT4 has a 2" lift over Denali.
I know the running boards are different. I was told the Denali has a drivers lumbar that moves up and down. Etc.

The AT4HD does not have a lift. Maybe different size tires, but that would be all that's different in height.

I don't think your dealer knows what they're talking about. It's the same exact truck minus badging, chrome and stitching. 2" level is only relevant to the AT4X. The running boards same or different is irrelevant most of those running boards are made by AMP anyway. If you don't have the power running boards then they are probably the heavy duty ones with bedliner material like I have.

You are chasing a ghost.
