Just purchased a 2024 GMC 1500 AT4 Carbon Pro DURAMAX. I am switching from a 2022 Ram 2500 Power Wagon. I intended to get an AT4X, but the guy in front of me when I pulled in had just purchased it. I am very happy with the regular AT4. I knew nothing about the Carbon Pro until I watched some YouTube videos on it after I purchased the vehicle. Finally found a bed cover that works with it and ordered it yesterday. Went with the Tri-Fold BAKFlip MX4 Tonneau Cover. Look forward to learning about this truck from this forum.
