2020 GMC Sierra 2500HD AT4 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
I purchased a 2020 Sierra 2500HD AT4 (Duramax) in November of 2020. This thing is a BEAST and a joy to drive. I've put almost 131K miles on it thus far and have not had a single issue. IMHO, the interior is better than a Ford but trails behind the Dodge. However, just because it seems less capable with technology isn't necessarily true. I have physical switches for many things that … the Dodge incorporates in their big screen. I MUCH prefer the switches because I don't have to go through electronic pages to find what I'm looking for. The seats are a bit hard but are very supportive. I'm averaging a 21mpg with it at this point but the majority (80%) of my driving is highway speeds. In an attempt see just how good of gas mileage I could get, I drove a cruise controlled speed of 55 mph on a VERY flat 2 lane road for a little over 75 miles. My results, 29.3mpg, yep, you read that right. As I get up to interstate cruising speed it's much closer to 22mpg. I have hauled my 6,000 pound boat a couple of times with it and it still gets around 14mpg. Speaking of hauling the boat, this thing tows like a dream. The cameras, mirrors and tow-haul mode work great and if I couldn't see the boat in my mirrors, I would hardly know it's there. The voice command menu and responsiveness is great, no issues with it and it has always recognized what I'm asking for. The Bose speakers produce more than I can listen to, and the cab is quiet enough for conference calls when I'm travelling for work. The in-cab outlet is perfect for charging my laptop on the go and allows my wife to use the computer when we travel without killing the battery. I put a hardcover on the bed but with the multipro tailgate I rarely have to do anything with it, and I make a LOT of trips to the lumber yard for 8'+ lumber. All I have to do is drop the upper portion of the tailgate and the long lumber slides right in and is safe and secure. One thing I would criticize. It doesn't match up when compared to the other makers off-roading capabilities (manual/push button locking differentials), but I didn't really buy it for that. If you want something to do some relatively challenging off-road cruising, look elsewhere. I could go on, but suffice it to say that I LOVE this truck and would absolutely recommend it without hesitation.
Awesome ridding truck

2020 GMC Sierra 2500HD AT4 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
If you want to go from a 1/2 ton to a 3/4 ton for towing your larger than 30’ travel trailer, this is an excellent choice. The new 6.6 gas motor will give you convenience towing any bumper pull trailer. If pulling the heavier 5th wheel trailers you probably want to go with the diesel. This truck with the gas motor rides really nice towing and empty. Don’t expect 1/2 ton gas mileage. I’m … getting around 15 -16mpg highway and 12-14 city. My last truck was a 2011 6.2 Ltz 1/2 ton some performance upgrades. Long tube headers ,cold air intake levelling kit and larger tires with 20”wheels. I was getting about the same gas mileage . But had to use premium gas. When towing my 30’ travel trailer the 2500 gets between 9&10mpg (based on a 1500 mile round trip) I have owned 7 gm trucks over the last 40 years, all purchased new except 2 that were low mileage. All gas V8s, and never had any motor or transmission problems. Towed boat,snowmobile,cargo,utility,tent ,horse and travel trailers over the years. Hopefully this helps anyone trying to decide if this is the right tow rig for you. Ps I worked on the line in gm Oshawa for 46 years,if you were wondering why all the gm trucks lol.
Good looking Beast

2023 GMC Sierra 2500HD Denali 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
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. Three years in and still haven’t cracked the 10k mark but very close. No issues with truck whatsoever. It is very underutilized I know and I realize a smaller truck will pull my camper but nowhere near as easily as this baby does. I have thought about trading it in but haven’t decided yet.
Great truck

2020 GMC Sierra 2500HD Denali 4dr Crew Cab 4WD LB (6.6L 8cyl 6A)
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.
