When you're shopping for a serious towing truck, the numbers matter—but understanding what those numbers actually mean matters more. The 2026 RAM 2500 Big Horn and Toyota Tundra SR5 represent different engineering philosophies, different price points, and dramatically different towing capacities.
Ken Ganley CDJR Norwalk works regularly with buyers comparing these trucks, and the answer is surprisingly one-sided once you look at actual specifications. The RAM 2500 Big Horn pulls significantly more weight, but the real question isn't just capacity—it's whether that capacity matters for your actual towing needs.
The Towing Spec Reality
The 2026 RAM 2500 Big Horn equipped with the Cummins diesel engine and appropriate drivetrain configuration delivers maximum towing capacity of 18,590 pounds. The gasoline-powered version tows 14,300 pounds maximum. These aren't theoretical numbers—they're SAE-certified capabilities that RAM trucks legitimately achieve.
The Toyota Tundra SR5 maxes out at approximately 11,700 pounds with its standard V6 engine. That's a significant gap. The RAM 2500 Big Horn's diesel capacity exceeds the Tundra's by roughly 7,000 pounds—the equivalent of a fully equipped bass boat plus trailer.
Why the Difference Exists
The RAM 2500 is purpose-built as a heavy-duty truck. Its frame is heavier. The suspension is designed specifically for serious towing loads. The Cummins diesel produces substantially more torque—926 lb-ft in the 2026 model year. That torque translates directly to pulling power, especially when loads require acceleration or climbing grades.
The Tundra is a capable light-duty truck. It's genuinely competent at towing mid-range loads. But it's engineered as a general-purpose truck—doing many things well rather than specializing in towing the way the RAM 2500 specializes.
That engineering difference explains the towing gap. It's not marketing exaggeration. It's fundamental design difference.
Payload Considerations
Towing capacity tells only part of the story. Payload capacity—how much weight you can carry in the truck bed—matters equally for real-world usage.
The RAM 2500 Big Horn delivers payload capacity of 2,250 pounds with standard configuration. That means you can carry significant gear in the bed while towing the maximum load. You're not choosing between bed cargo and trailer load.
The Tundra SR5 provides approximately 1,400-1,500 pounds of payload capacity. That's meaningful but considerably less. If you're towing maximum capacity with the Tundra, your bed cargo options become very limited.
Engine and Drivetrain Impact
The RAM 2500 Big Horn offers genuine options. The 6.7L Cummins diesel dominates for serious towing. It produces 400 horsepower and that substantial 926 lb-ft torque. But the 6.4L HEMI gasoline engine—producing 410 horsepower and 429 lb-ft torque—provides a legitimate alternative if diesel fuel costs or service accessibility concerns you.
The Tundra's V6 engine is the only towing option. It's adequate for the Tundra's towing class but doesn't offer alternatives.
Brake Systems and Safety
The RAM 2500 comes standard with integrated trailer brake controller and advanced braking systems designed for heavy loads. When you're towing 18,000+ pounds, brake performance becomes a genuine safety consideration. The RAM 2500's braking system is engineered specifically for that weight range.
The Tundra's braking system handles 11,700 pounds competently but operates in a different capability range. Maximum stopping distance from highway speed with maximum load differs significantly between these trucks.
Suspension Design for Serious Work
The RAM 2500's leaf-spring suspension with heavy-duty shocks and air springs handles maximum towing loads while maintaining control. This isn't luxury-car comfort, but it's predictable and reliable for work.
The Tundra uses an independent double-wishbone rear suspension. It provides smoother highway riding when lightly loaded but performs differently under maximum towing loads. The engineering choices reflect different priorities.
Real-World Towing Scenarios
If you're towing a 20-foot enclosed trailer with equipment to a job site several times monthly, the RAM 2500 Big Horn handles it as designed. You're within comfortable capability range with margin for safety.
The same scenario pushes a Tundra near or beyond maximum capacity. You're operating closer to limits, which means less margin for unexpected loads or unforeseen weight additions.
When Maximum Capacity Isn't Necessary
This comparison might seem heavily favoring RAM, but context matters. If you're towing a small travel trailer occasionally or a boat a few times yearly, the Tundra's 11,700-pound capacity genuinely suffices. You don't need 18,590 pounds. You're paying for capability you won't use.
Price difference reflects that reality. The Tundra starts lower. The RAM 2500 Big Horn costs more because it delivers engineering and capability for significantly heavier work.
Exploring Your Options
If you're considering different truck options within RAM's lineup, the 2024 Jeep Gladiator represents a different truck category—lighter duty but with different advantages for specific uses. Understanding how different trucks address different needs helps clarify which matches your actual requirements.

The Honest Comparison
The RAM 2500 Big Horn tows significantly more than the Tundra SR5. That's not opinion—it's engineering fact. Whether that additional capacity matters depends entirely on your actual towing requirements. Choose the truck that genuinely matches what you need to pull, not the one with the biggest number.
