The 2023 Sierra 2500HD is a seriously capable heavy-duty truck. The large cabin fits passengers and cargo without issue. Hauling and towing capacities are strong, just as you'd expect from a truck in this class. The available MultiPro tailgate also makes loading items into the bed easy. But a few things are holding the Sierra back, such as poor ride quality, below-average visibility, and in-cabin tech that doesn't match up with the tech in segment leaders.

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.

2020 GMC Sierra 2500HD Denali 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
After 43K miles I'm selling my Year 2020, 2500 HD Denali, 6.6 l diesel. Replaced the diesel particulate filter at 20K miles for $1500. The particulate heater (burner) just died at 43K miles for another $1500. Waiting 2 weeks for parts while the truck sits. After 50K miles, I will pay these repair bills instead of GMC. i am on first name basis with service dept. No thanks. I'm out.
