Engines: Duramax vs. Cummins, Plus the Gas Options
Both trucks give you a gas choice and a diesel choice. The Silverado 2500HD offers a 6.6-liter gas V8 or the 6.6-liter Duramax turbo-diesel V8. The Ram 2500 offers a 6.4-liter HEMI gas V8 or the 6.7-liter Cummins turbo-diesel inline-six.
Most of the time, the bigger decision isn't Chevy or Ram. It's gas or diesel. A diesel costs more up front, but it earns its place when you're towing heavy most days, stacking up highway miles, or pulling the same equipment trailer week after week. If your truck mostly makes short hops around Dallas–Fort Worth with lighter loads, a gas V8 keeps things simpler and easier on the purchase price.
Ride, Suspension, and How They Handle a Load
Here's a difference you'll notice on your first Silverado 2500HD vs. Ram 2500 test drive. The Ram 2500 uses a coil-spring rear suspension, while the Silverado 2500HD sticks with a traditional leaf-spring setup.
Coil springs tend to ride smoother when the bed is empty, which matters if your crew spends hours a day in the cab between jobs. Leaf springs are the time-tested heavy-duty design for carrying weight. Neither is wrong. It comes down to whether your truck spends more of its day loaded or running empty between stops.
If you're comparing the Ram 2500 Tradesman vs. Silverado 2500HD Work Truck trims specifically, both are the no-frills, work-first versions that fleets and upfitters tend to start from. Equipment varies from build to build, so compare the window stickers line by line instead of assuming they match.
Which One Fits Your Business?
If you're hunting for the best 3/4 ton work truck for your crew, start with what's going in the bed and what's behind the hitch. A few common situations:
• Service trades with a utility body. Plumbers, electricians, and HVAC techs often add a service body. Both trucks can be upfit, so the right pick depends on the body you need and how the truck is configured underneath it.
• Crews that live in the cab. If your team rides together for hours, the Ram's coil-spring rear is worth a back-to-back test drive against the Silverado.
• Heavy daily towing. Look hard at diesel on either truck, and confirm the exact tow rating for the configuration you're buying, not just the brochure maximum.
Shopping for a 3/4 ton truck for towing equipment? Weigh your loaded trailer before you buy. Tow ratings change with cab style, bed length, engine, and axle ratio, so the biggest number in the brochure may not apply to the truck on the lot. Our fleet team can match the rating on a specific truck to your actual trailer.
Frequently Asked Questions
Which is better for towing, the Silverado 2500HD or the Ram 2500?
Both are built for serious towing, and the answer depends on configuration. Engine, axle ratio, cab, and bed all change the rating, so compare the exact trucks you're considering against your loaded trailer weight.
Should I get a gas or diesel three-quarter-ton truck?
Diesel makes the most sense for frequent heavy towing and high mileage. For shorter local routes with lighter loads, a gas V8 usually costs less up front and keeps things simpler.
How do the Silverado 2500HD and Ram 2500 ride differently?
The Ram 2500 uses a coil-spring rear suspension, which many drivers find smoother with an empty bed. The Silverado 2500HD uses leaf springs, the traditional heavy-duty design for hauling weight.
Can I compare both trucks at the same dealership?
Yes. Huffines Fleet sells both Chevrolet and Ram commercial trucks, with locations in Lewisville and Plano, so you can drive them back to back and work with one fleet team on both.
