WHAT A TRUCK
Bill S., 04/06/2020
2020 GMC Sierra 3500HD Denali 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
I purchased this Denali two weeks ago. I absolutely love this truck. The ride is so smooth and power band is incredible. What a huge difference between my 2008 GMC 2500HD Duramax, its like night and day... I love all the high tech features with the 2020's from the cameras to the front and rear LED lighting. Oh yea forgot about that first of its kind tailgate. Now that's a very … useful tailgate, I can see Ford, Dodge and Chevrolet using the same basic tailgate in the near future. I really cant wait to haul my 5th wheel with this truck. Once I make that first trip I will update this review regarding the towing... A big thank you for Thompsons GMC in Placerville, CA for such a great purchasing experience. It’s been about a year since I purchased my GMC 3500 Denali and wanted to update my review. I still love this truck so much. I’ve towed my 5th wheel RV approximately 8000K miles. This truck tows my 5th wheel like a dream. The cooling system is definitely a 100% improvement over my 2008 while towing in the warmer weather. About the only thing I’d like to see is GM add more information to the heads up display (HUD) like your blind spot indicators. I’m glad we bought when we did because I hear that dealers are having a tough time receiving new trucks. Bottom line is this, I’d buy this truck all over again absolutely No Regrets!!!!

2020 GMC Sierra 3500HD Denali 4dr Crew Cab 4WD SB (6.6L 8cyl 6A)
In my 3rd year of owning the new 2020 GMC 3500 HD Denali after replacing my 2012 F250. Choose the GMC because I did not care for the new Ford styling. I still can not believe this is a HD 3500. While commuting around town, I think I am in my wife's German SUV because the ride and amenities are excellent. Visibility and Camera system are great and the interior seats comfortable and … supportive. When I hooked up the 3x axle boat and set out to the lake I was amazed at the poise and power. It made towing enjoyable! I really like my F250, but this truck is awesome.
Over 112 days in the shop & counting!

2022 GMC Sierra 3500HD Pro 4dr Crew Cab 4WD LB DRW (6.6L 8cyl 6A)
I am a sole proprietor of Vintage Rides Garage & Vintage Rides, LLC. I purchased 2022 GMC Sierra 3500hd in Elk City Oklahoma Sept 24, 2021 during the "CHIP" debacle. It was purchased to avoid being stranded on the side of the road on a long haul. After many trips and 98,387 miles. On July 8, 2023 I head what sounded like a flat tire. I pulled off the highway and found it was coming from … the engine compartment. It being a Saturday I called for a flatbed tow waiting to take to the dealership on Monday July 10th, 2023. After 45 plus days and the truck not throwing any codes they had a factory rep out to evaluate the issue. The crank shaft had an issue and metal was throughout the engine. They replaced engine with a new factory Duramax and took me for a ride. During the ride the service manager and I witnessed a hard shimmy/shake. Now it appears 112 days at the shop after using the original injection system & turbo, they replaced several injectors and are planning on adjusting valves. If the issue persists they will order yet another engine and start the process over. All the while my business has lost its only means of revenue and I still have to pay my truck payment that is $1000 a month plus commercial insurance $1,068 a month with no end in site with no concern from GM or the Local Dealership. I will wait it out sell it when ready I guess I'm a no longer a GM man. Mike G. Vintage Rides Garage USDOT-3261352 MC-1035008 Red Bluff, CA
Incredible

2020 GMC Sierra 3500HD Denali 4dr Crew Cab 4WD LB DRW (6.6L 8cyl 6A)
After waiting for several months and production delays I was finally able to get my hands on a 2020 3500 Denali DRW and I have to say that this truck was well worth the wait. It drives smoother than any truck I've ever owned and the safety features are incredible. I have absolutely no complaints and with it being a Denali there really isn't any more stuff I will need to add. (other than … a fifth wheel hitch) I love the 10 speed transmission and the 6.6 diesel has more than enough HP and torque. GMC hit it out of the park!
