CarGurus Analysis: 2020 GMC Sierra 3500HD
Summary
With 68 currently listed for sale and an average price of $61,733 CAD, 30.9% of 2020 GMC Sierra 3500HD listings on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2020 GMC Sierra 3500HD 5 / 5 stars.
Why it stands out
The 2020 GMC Sierra 3500HD stands out as a heavy-duty truck that blends serious capability with a more polished feel than many work-focused rivals. It debuted as a 2020 model with revised styling, a larger footprint, and only minor changes inside, but its biggest advantage was a significant increase in maximum towing capacity. GMC also kept the Sierra 3500HD flexible, offering a wide range of cab, bed, and dual-rear-wheel configurations to suit both jobsite duty and more specialised towing needs.
Power comes from two 6.6-litre V8 options: a gasoline engine with 401 horsepower and 464 pound-feet of torque, or a Duramax turbodiesel V8 with 445 hp and 910 lb-ft of torque. The diesel is paired with a 10-speed automatic transmission, while the gas engine uses a six-speed automatic. When properly equipped, the truck can haul up to 3,375 kilograms and tow up to 16,100 kilograms, though those figures require the diesel engine, a single cab body, rear-wheel drive, a gooseneck hitch, and dual rear wheels. Buyers also get a broad trim walk, from a basic work truck to the Denali, plus useful towing and safety technology such as trailer hitch guidance, Apple CarPlay and Android Auto, forward collision alert with automatic emergency braking, and available blind-spot monitoring.
For shoppers, the appeal is straightforward: the 2020 Sierra 3500HD offers immense towing and hauling ability, a more refined upper-trim experience, and enough technology to make heavy-duty work easier. It is not without drawbacks, though. The truck can be unwieldy in parking lots, top trims can be very expensive, and rivals typically can tow more. Even so, for buyers who want a capable one-ton truck with a strong mix of strength, comfort, and available luxury, it remains a compelling choice.

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!

Owners consistently praise its heavy-duty performance, especially when pulling heavy loads, and they also describe it as comfortable and well-built. It is a strong fit if you want a capable one-ton truck with a more polished feel than many work-focused rivals, and the 31.0% share of good or great deals suggests there is still some market value to be found.
Is the 2020 GMC Sierra 3500HD reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The owner feedback also highlights a dependable, trouble-free feel in day-to-day use, with many shoppers saying they trust it more than competing heavy-duty trucks from Ford and Ram.

What is the 2020 GMC Sierra 3500HD's resale value?
The current average of $61,569 CAD sits slightly below last year's $63,956 CAD.
That softer pricing suggests future sellers may need to stay competitive if they want to move the truck quickly. If the market continues to favour buyers, resale values could remain under some pressure in the near term. Still, the truck’s strong owner satisfaction helps support demand when you eventually decide to sell.
Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2020 GMC Sierra 3500HD or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 31.0% of listings are priced as good or great deals.
- Price trend: Prices have softened 3.73% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
The bottom line: If you want the better balance of current pricing, owner satisfaction, and available inventory, the 2020 is the primary year to target. If you are especially price-sensitive, you can still compare nearby years, but the 2020 stands out as the more compelling all-around choice for shoppers who want heavy-duty capability without paying top dollar.
