Hi, I would like to introduce myself. My name is Doug and I am new to this forum and a new AT4 owner as well. I just purchased a new 2026 1500 AT4 yesterday with the 3.0 duramax. I absolutely love the truck and figured I would join here to learn more about maintenance, do's and don'ts, and future upgrades, etc...that I can do along the way to keep this truck in the best shape possible. Thanks for the add and looking forward to your experiences and recommendations.
