Should I buy a used GMC Sierra 3500HD now or wait for the next model?

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 2026 GMC Sierra 3500HD stands out as a heavy-duty truck that blends serious work capability with a wide spread of trims and equipment. It can be configured with a regular cab, an extended cab, or a crew cab, and buyers can choose between a 6’10” short bed or an 8’2” long bed, plus either single- or dual-wheel rear axles. Under the hood, it offers 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 can haul as much as 7,442 pounds of cargo and tow up to 35,500 pounds.
What makes the 2026 Sierra 3500HD especially appealing is how much its trim walk changes the truck’s personality. The base model is stripped down and work-focused, while the SLE adds conveniences like power-adjustable tow mirrors, remote keyless entry, a wifi hotspot, and cruise control. The SLT brings the MultiPro tailgate, trailering assist features, leather upholstery, heated front seats, and dual-zone automatic climate control, while the AT4 adds off-road hardware such as all-terrain tires, skid plates, a locking rear differential, and unique off-road drive modes. At the top, the Denali emphasizes luxury with premium leather, a native navigation system, a wireless phone charger, a larger eight-inch touchscreen, a Bose premium audio system, and parking proximity sensors.
For 2026, the MultiPro tailgate was also available with more models, adding another useful feature to an already versatile lineup. The Sierra 3500HD’s strengths are clear: impressive towing and hauling ability, smart towing technology, and higher trims that feel genuinely upscale. Its main drawback is that, like other heavy-duty trucks, it remains a large and demanding vehicle to live with, especially in tight parking situations.
