The base Pro trim starts at $51,995 for the 2500, and $53,195 for the 3500. This trim comes equipped with a trailering package, allowing you to tow the moment you get it. When operating the HD on less than ideal terrain, then the automatic locking rear differential should prove useful.

Yes, the Sierra HD saw some updates. There are a few features that now come standard either across the entire lineup, or are now standard on a lower trim level. The feature now standard across the lineup is a trailer-brake controller. This makes it easier for you to remain in control at all times.
The next feature that you can find that is available at a lower level is the Adaptive cruise control with trailering assist. It was available on the upgraded Denali and AT4 trims, but is now available on the base variants as well.
What are the 2025 GMC Sierra HD specs?
