Reviewed a 2023 GMC Pro Crew Cab 4WD on Nov 12, 2025
Great for a work Truck and daily driver. Not quite as luxurious as my Denali. I believe the next time I will pick the better option for 360° cameras as my eyesight is not as good as it used to be. Fuel mileage is just under 14 empty. I have not started pulling anything with it yet.
