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. UPDATE: I absolutely love our 2021 2500HD 6.6 litre Diesel. It pulls our 30 foot travel trailer (7,000 lbs empty) like a dream. The 10 speed transmission is extremely smooth. I find the interior very roomy, comfortable and quiet, which is noticeable on longer road trips. Ours is the SLE model but with the Kodiak package, which adds lots of nice upgrades. I've always been a GM man so can't compare to Ford or Dodge but can't think of anything negative with our GMC.
