    Love Our 2500 HD Diesel

    We have no regrets with our 2021 GMC 2500 HD Diesel. The mileage is around 25 mpg on the highway which is excellent when not pulling a trailer. It obviously goes down when pulling our trailer, however the power & torque that the diesel puts our coupled with the 10 speed transmission is amazing & well worth it in my mind. We have cloth seats & find them very comfortable. Very spacious inside. Quiet ride.
