The 2026 Ram 3500 tows up to 36,610 lb (16,606 kg) when equipped with the available High-Output 6.7L Cummins Turbo Diesel I6. For Ottawa-area buyers hauling fifth-wheel campers, horse trailers, or heavy construction equipment, the Ram 3500 handles the kind of work that pushes a half-ton well past its limits.
That headline number, though, depends entirely on how you configure the truck. Engine choice, axle setup, single rear wheel (SRW) versus dually (DRW), and hitch type all shift the tow rating you’ll actually achieve. Here’s what you need to know before you spec your build.
How the 2026 Ram 3500 Reaches Its Maximum Tow Rating
The 36,610 lb conventional towing maximum requires the available High-Output 6.7L Cummins Turbo Diesel I6 and proper equipment. That phrase “when properly equipped” appears on every Ram spec sheet for good reason, your actual tow rating shifts based on several configuration factors working together.
Engine Choice and the Cummins Diesel
The 6.7L Cummins Turbo Diesel I6 is the engine tied to the 2026 Ram 3500’s maximum tow figures. A High-Output version of this diesel is available and delivers the torque needed to move serious loads. Ram does not publish a gasoline engine option in the current Canadian 3500 lineup, so the Cummins diesel is your towing powerhouse for the 2026 model year.
The diesel also pairs with trailer-specific features like Electronic Trailer Brake Control. These systems work together to keep heavy loads stable on Highway 417 or on any stretch of road between Kanata and your worksite.
Single Rear Wheel vs. Dually
This is where many buyers need clarity. SRW trucks have one tire per side in the rear. DRW (dually) trucks have two tires per side. The wider rear stance of a dually spreads trailer tongue weight across more rubber and a broader contact patch.
DRW configurations generally achieve higher tow ratings than SRW setups. If you’re pulling a large fifth-wheel RV or a loaded gooseneck trailer, a dually is typically the right call. For lighter loads or tighter job sites, SRW offers easier manoeuvrability. If you’re still deciding between a heavy-duty and a light-duty platform, the 2026 Ram 1500 vs. 2500 towing comparison is a useful starting point.
Hitch Type Matters
Ram publishes the 36,610 lb figure for conventional towing. Fifth-wheel and gooseneck hitch ratings are separate figures. Because the hitch point sits over the rear axle rather than behind it, weight distribution changes significantly.
Buyers towing horse trailers or large flatdecks on a gooseneck setup should confirm their specific configuration’s rated capacity before purchasing. Review the towing guide for your exact build with a Capital Dodge product specialist.
Weight Figures Every Buyer Should Know
The question of how much a Ram 3500 weighs is the natural companion to towing questions. Three numbers matter: curb weight, Gross Vehicle Weight Rating (GVWR), and payload.
Curb weight is what the truck weighs empty. GVWR is the maximum the truck can weigh fully loaded, including passengers, cargo, and tongue weight from a trailer. Payload is the difference between the two.
Ram does not publish a single curb weight or payload figure for the 3500 because these numbers change with every cab, bed, engine, and axle combination. Every kilogram of payload you use for passengers and cargo reduces the tongue weight your truck can handle, and that directly affects your safe towing capacity.
Your build sheet will list the exact GVWR and payload for your specific configuration. Ask for it before you buy.
Why Configuration Matters for Ottawa Buyers
Ottawa’s mix of highway commuting, rural properties, and four-season weather makes choosing the right Ram 3500 setup especially important. Towing a fifth-wheel to Algonquin Park in July is a very different ask than hauling construction materials through a February snowstorm on County Road 17.
For the 2026 model year, Ram 3500 Crew Cab models offer an available 189 L (50 U.S. gallon) fuel tank. Fewer fuel stops mean more time on the road during long hauls across Eastern Ontario.
The Ram 3500 also comes with Adaptive Cruise Control with Automatic Braking as standard equipment on the Tradesman trim, along with Trailer Brake Control. These features help manage heavy loads in stop-and-go traffic around the Queensway or on longer highway runs. Ram backs the 3500 with solid warranty coverage, including dedicated protection for the Cummins diesel. Confirm specific terms with your dealer, as coverage details can vary.
For buyers also considering the Ram lineup’s lighter-duty options, current Ram 3500 inventory at Capital Dodge shows what’s available in the Ottawa area right now.
How to Spec the Right Ram 3500 for Your Trailer
Choosing the right configuration comes down to three questions: What are you towing? How heavy is it when loaded? How often will you tow it?
For buyers pulling trailers under 20,000 lb occasionally, an SRW setup with the Cummins diesel may handle the job well. For those regularly hauling near the 36,610 lb maximum, the High-Output Cummins on a DRW chassis is the configuration to discuss.
As of 2026, Ram offers five trims for the 3500 in Canada: Tradesman, Big Horn, Laramie, Limited, and Limited Longhorn. The trim you choose affects comfort and technology. The powertrain and axle configuration you choose affects towing capacity. Both decisions work independently of each other.
Book a service or towing consultation at Capital Dodge to match your trailer’s specs with the right Ram 3500 build. Bring your trailer’s weight sticker or manufacturer specs for the most accurate recommendation.

Frequently Asked Questions
How much can a 2026 Ram 3500 tow?
When properly equipped with the available High-Output 6.7L Cummins Turbo Diesel I6, it can tow up to 36,610 lb (16,606 kg) conventional. That maximum requires the right combination of engine, axle ratio, and configuration. Your actual tow rating depends on whether you choose SRW or DRW and which hitch type you use. Contact Capital Dodge in Ottawa to confirm the exact figure for your preferred build.
How much does a 2026 Ram 3500 weigh?
Curb weight varies by cab size, bed length, engine, and whether you choose SRW or DRW. Ram does not publish a single curb weight because every configuration is different. Your GVWR and payload rating appear on the build sheet for your specific truck. Ask your Capital Dodge advisor to walk you through the numbers for the configuration you’re considering so you can plan your load safely.
What is the difference between SRW and DRW on the Ram 3500?
SRW means single rear wheel, one tire on each side of the rear axle. DRW, or dually, adds a second tire on each side. The dually’s wider stance distributes trailer weight more evenly and generally supports higher tow ratings. Heavy fifth-wheel or gooseneck trailers pair well with DRW setups. SRW trucks offer easier parking and daily driving comfort when you’re not towing near the maximum.
Does the 2026 Ram 3500 come with trailer assist features?
It does. Adaptive Cruise Control with Automatic Braking is standard on the Tradesman trim, and Trailer Brake Control is available across the lineup. Electronic Trailer Brake Control helps manage stopping distances with a loaded trailer. These features work together to make towing in highway traffic and varied weather conditions around Ottawa more manageable. Check with Capital Dodge for the full list of towing technology on your preferred trim.
What engine does the 2026 Ram 3500 use for maximum towing?
The maximum tow rating of 36,610 lb requires the available High-Output 6.7L Cummins Turbo Diesel I6. This inline-six diesel produces the torque needed for heavy conventional towing. Ram also offers a standard-output version of the Cummins diesel. For details on how each engine option affects your specific tow rating, visit Capital Dodge in Kanata and review the towing guide with a product specialist.
How does hitch type affect 2026 Ram 3500 towing capacity?
Conventional, fifth-wheel, and gooseneck hitches each carry different tow ratings because they distribute trailer weight differently. The 36,610 lb maximum published by Ram applies to conventional towing. Fifth-wheel and gooseneck ratings are separate figures. Because the hitch point location changes how weight transfers to the truck’s frame and axles, confirm the rating for your specific hitch type before purchasing a trailer or truck configuration.
What fuel tank size is available on the 2026 Ram 3500?
Crew Cab models offer an available 189 L (50 U.S. gallon) fuel tank. For long-haul towing across Ontario, Ottawa to Thunder Bay or anywhere in between, that capacity means fewer stops and more uninterrupted driving time. Ask your dealer whether your preferred cab and bed combination qualifies for this larger tank option.
