Love the looks, love the power, love the economy
Rick B., 03/18/2021
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.
