This truck was in pristine condition, exactly what I was after in a vehicle. I passed on it because the asking price was pretty much what it was worth new in 2015. I have a hard time paying that kind of money for a 11 year old truck.

Besides the bells and whistles we grabbed this dually because we pull a toy hauler. We went from a sturdy 2500 Dodge Ram to this beauty. We choose the dually 3500 due to the pulling capacity and payload as toy haulers are heavier in front to compensate for the weight that you can put in the back. We have no issues pulling it now and the truck does not squat because the support of the 4 tires. Other friends have regular 3500 and still have issues with the payload and had to put in more money into their vehicle to beef up the suspension when pulling a toy hauler because the payload is less. YOU WONT REGRET BUYING ONE!

Why it stands out
The 2020 GMC Sierra 3500HD stands out as a heavy-duty truck that was redesigned for greater capability without abandoning its work-truck roots. It debuted as a 2020 model, grew by as much as 10 inches in length and 2.5 inches in height, and adopted a slightly larger, blockier grille. The changes were modest inside, but the truck’s maximum towing capacity rose sharply, with its most extreme case increasing by 53 percent. Buyers also got a wide range of cab, bed, and rear-axle configurations, which helped make the Sierra 3500HD adaptable for both jobsite duty and more specialized towing needs.
Power and equipment are central to its appeal. The 2020 Sierra 3500HD offered a 6.6-liter V8 with 401 horsepower and 464 pound-feet of torque, or a 6.6-liter Duramax turbodiesel V8 with 445 hp and 910 lb-ft of torque. Properly equipped, it could haul up to 7,442 pounds and tow up to 35,500 pounds. Even the base truck came with a seven-inch infotainment touchscreen plus Apple CarPlay and Android Auto, while higher trims added features such as the MultiPro tailgate, trailering assist technology, off-road hardware, and luxury touches like leather upholstery, a larger touchscreen, and a Bose audio system. For buyers who want a serious tow rig that can also feel modern and well-equipped, that combination is a major strength.
There are tradeoffs, though. The base model was intentionally sparse, and the truck’s size can make it unwieldy in parking lots. Top trims can also become very expensive, and the truck’s rivals typically can tow more. Even so, the 2020 GMC Sierra 3500HD remains distinctive for blending heavy-duty capability, broad configuration choices, and a more refined upper-trim experience than many buyers expect from a one-ton workhorse.
