The truck in itself is wonderful. It uses way too much DEF fluid when pulling a trailer. The stiffer Springs in the rear are causing a rough ride with a trailer. Great power, love the camera system, love the handling, very quiet.

Still new but love the technology and the ride. I will report more after I have more miles driving it. It is not my daily driver so after 6 months I have only 1100 miles on it. So far so good it drives great, loads of acceleration, comfortable what else could you want. It’s big so naturally it is cumbersome to park but the cameras make that manageable. The only knock other than too much plastic in the interior is with the big tow mirrors there is a blind spot when looking to the right towards the roof pillar. That’s because the tow mirror is right behind it and that blocks your view. It is not unworkable but a minor annoyance just the same. After a year of owning it still only an occasional driver with a little over 3000 miles on it. I took a camping trip and it pulled my 25 ft camper with ease. It really shines when towing and you have an appreciation of the trucks size and power. So far the only negative was on that trip my HUD quit working. A minor annoyance and when I take it in for service I will have it fixed. Well as it turned out the HUD didn’t fail I apparently didn’t realize I accidentally turned the HUD position too far down and didn’t know how to turn it back up. So basically operator error. I still have a little over 7 thousand miles on it and have taken it camping a few times and it pulls my camper with ease. Bottom line is it is a great truck. Over two years old and almost 9k miles without any problems and the thing I love the most about this truck is the power. Man this truck is big but if you mash the gas it will fly. I am a little embarrassed to say the HUD issue I posted in the review turned out to be operator error. Somehow I must have bumped the button that positions the HUD display up and down and turned it all the way down making it disappear from the windshield. Anyway it was working all along so moving right along and like I mentioned before it is not my daily driver. I have a little over 6k on it and zero problems. It drives and rides like a dream.

I've owned and operated many different trucks for either work or home and I'm constantly surprised by the performance, reliability and security this truck has to offer. It wasn't cheap but you really can't put a price on safety and comfort while towing a trailer long distances. The improvements GM made from 2019 to 2020 are significant and would strongly suggest you do your research before purchasing a different truck - they're not all created equal. Buy with confidence. I'm a believer and will never go back.

Everything you could expect in a heavy duty truck. Ride is good mileage is great features good… could use an upgrade on the screen soon but that’s about it

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.
