Silverado 2500 HD & 3500 HD Duramax: The Heavy-Hauler Pick
If you tow a fifth-wheel to Highlands Hammock, pull a cattle or horse trailer down SR-66, or haul a skid steer between job sites, the Silverado HD with the Duramax 6.6L turbo-diesel V8 is the truck to beat. The current Duramax 6.6L makes 470 horsepower and 975 lb-ft of torque, paired with an Allison 10-speed automatic. A properly equipped 3500 HD dual-rear-wheel model is rated for up to 36,000 lbs of fifth-wheel or gooseneck towing, and conventional ball-hitch ratings reach 20,000 lbs on select 2500 HD and 3500 HD configurations. Not sure whether you need a three-quarter-ton or a one-ton? Our Silverado 1500 vs. 2500 vs. 3500 comparison walks through the differences in payload, towing, and ride quality.
Silverado 1500 3.0L Duramax: Diesel Torque for Everyday Driving
Not every Sebring driver needs a heavy-duty truck. If your week is mostly commuting on US-27 with a bass boat or utility trailer on weekends, the Chevrolet Silverado 1500 with the available 3.0L Duramax inline-six is often the smarter buy. It delivers 495 lb-ft of torque, a quieter cabin than a heavy-duty diesel, and the best highway fuel economy in the Silverado lineup — a real advantage for Highlands County drivers who put long miles on their trucks. One note for midsize shoppers: Chevrolet no longer offers a diesel in the current Chevrolet Colorado, so a midsize Duramax means shopping pre-owned.
How to Get the Best Price on a New Diesel Truck
Diesel engines are an option on top of the base truck price, so incentives matter. Check our current new Chevrolet specials before you shop, and ask whether you qualify for GM discount programs for military members, first responders, educators, and GM suppliers. For a deeper look at Silverado trims and pricing strategy, see our guide to the best price on a Chevy Silverado in Sebring. Heavy-duty diesel inventory moves quickly, so if the configuration you want is not on the lot, our team can locate one or place a factory order.

Used & Certified Pre-Owned Diesel Trucks Near Sebring
Which Used Duramax Model Years Are Worth Considering?
A pre-owned diesel can save you thousands, and Duramax trucks are known for lasting well past 200,000 miles when they are maintained properly. The 2017 and newer Silverado HD models use the L5P version of the 6.6L Duramax. Model years 2020 through 2023 pair it with the Allison 10-speed at 445 hp and 910 lb-ft, and 2024 and newer trucks — like the 2024 Chevrolet Silverado HD — step up to today's 470 hp and 975 lb-ft rating. For a midsize diesel, a 2016–2022 Colorado with the 2.8L Duramax offers up to 7,700 lbs of towing in a truck that fits in a Sebring garage. Longtime truck owners will understand why older Chevy trucks are so popular — they hold their value.
Certified Pre-Owned Diesel Peace of Mind
The biggest risk with a used diesel is the unknown: towing history, maintenance gaps, and emissions system wear. That is why many Sebring buyers start with certified pre-owned Chevrolet trucks. GM-certified vehicles pass a 172-point inspection and include factory-backed limited warranty coverage. Our CarBravo pre-owned program explains how certification works, and you can add a Chevrolet Protection Plan to cover turbochargers, injectors, and other costly diesel components beyond the factory warranty.
What to Check Before You Buy a Used Diesel
Whether you buy from us or anyone else, ask for maintenance records, look for a factory-installed fifth-wheel or gooseneck prep package if you plan to tow heavy, and confirm the diesel particulate filter and exhaust system have not been modified or deleted — deleted trucks can fail inspection and void warranty coverage. A clean vehicle history report helps too, which is why we highlight CARFAX one-owner vehicles. Call 888-511-2883 to ask which used diesel trucks are currently in stock.

Duramax Diesel Service Near Sebring, FL
Diesel Maintenance Is Different — and It Matters
Buying the best diesel truck is only half the equation; keeping it that way is the other half. Duramax engines need maintenance that gas trucks do not, including fuel filter and water separator service, diesel exhaust fluid (DEF) refills, and periodic checks of the diesel particulate filter and emissions system. Florida's heat and humidity make fuel-water separation especially important. Our Chevrolet service center uses GM-certified technicians trained on both the 6.6L and 3.0L Duramax, along with genuine GM parts and the correct diesel-rated fluids.
Common Diesel Truck Services We Handle
We perform certified oil changes using diesel-spec oil at the intervals your truck's Oil Life Monitor recommends. Heavy-duty trucks also work their batteries and brakes harder than most vehicles, so we test the dual-battery setup many Silverado HD diesels use through our battery service and inspect pads and rotors with our brake service — especially important if you tow near your truck's rated limit. Load-rated truck tires round out the list for drivers hauling heavy trailers.
Easy Scheduling for Sebring Truck Owners
Sebring drivers can book service online or call 800-930-5769. Service and Parts hours are Monday through Friday 7:30 AM to 5:30 PM and Saturday 8:00 AM to 2:00 PM, so you can drop off before work or on a Saturday morning. Have questions about intervals or warranty coverage first? Our service FAQ answers the most common ones.

Financing a Diesel Truck in Sebring, FL
Plan for the Full Cost of a Diesel Truck
A diesel truck usually costs more up front than the gas version, and diesel fuel and DEF add to your running costs. The payoff comes in towing ability, engine longevity, and resale value. Before you choose, it helps to see the monthly numbers side by side. The Huston Chevrolet finance center works with GM Financial and a network of lenders to find competitive rates and terms for new and used diesel trucks, whether your credit is excellent or still being rebuilt.
Should You Buy or Lease a Diesel Truck?
If you tow heavy and rack up miles, buying usually makes more sense, since leases come with mileage limits and wear-and-tear standards. If you want a newer Silverado every few years and drive moderate miles, a lease can lower your monthly payment. Learn more about leasing a Chevrolet in Avon Park, or compare both paths in our financing vs. leasing guide.
Approval Options and Rewards for Sebring Buyers
Worried about credit? Our car loan approval guide for Sebring explains your options step by step. Once you own your truck, Chevrolet rewards let you earn points on service visits and apply them toward future purchases — a nice perk for diesel owners who come in for regular maintenance.

Frequently Asked Questions — Best Diesel Trucks for Sale in Sebring, FL
What is the best diesel truck for sale in Sebring, FL? +
It depends on the job. For heavy fifth-wheel campers, horse trailers, and equipment, the Silverado 2500 HD or 3500 HD with the Duramax 6.6L turbo-diesel V8 (470 hp, 975 lb-ft) is the strongest choice, with up to 36,000 lbs of fifth-wheel/gooseneck towing on a properly equipped 3500 HD. For daily driving with occasional towing, the Silverado 1500 with the 3.0L Duramax (495 lb-ft) balances capability and fuel economy. Huston Chevrolet in Avon Park, about 15 minutes north of Sebring on US-27, sells both, new and pre-owned.
Does Chevrolet still make a diesel Colorado? +
No. The 2.8L Duramax diesel was offered in the Chevrolet Colorado from the 2016 through 2022 model years. The current-generation Colorado is gas-only, so shoppers who want a midsize diesel pickup need to look at used Colorado Duramax models.
Should I buy a diesel or gas truck in Highlands County? +
A diesel usually makes sense if you tow heavy loads often, drive long highway miles, or keep trucks for many years. If you mostly drive around town and tow light loads occasionally, a gas engine typically has a lower purchase price and simpler maintenance. Many Sebring-area buyers who haul campers to state parks or pull equipment on ranch land prefer the Duramax diesel.
Can I get a used diesel truck near Sebring with a warranty? +
Yes. Certified pre-owned Chevrolet trucks at Huston Chevrolet pass a 172-point inspection and include factory-backed limited warranty coverage. Optional Chevrolet Protection Plans can extend coverage beyond the factory warranty for diesel components.
Does Huston Chevrolet service Duramax diesel trucks from Sebring? +
Yes. Huston Chevrolet's GM-certified technicians service Duramax 6.6L and 3.0L diesel engines, including oil changes, fuel filter replacement, diesel exhaust fluid top-offs, and emissions system diagnostics. Sebring drivers can book online or call 800-930-5769.
How much can a Silverado HD diesel tow? +
When properly equipped, the current Silverado HD with the Duramax 6.6L is rated for up to 20,000 lbs with a conventional hitch and up to 36,000 lbs of fifth-wheel or gooseneck towing on a 3500 HD dual-rear-wheel model. Actual capacity depends on cab, bed, axle, and drivetrain configuration, so always check the specific truck's trailering label.
Is a diesel truck worth it for Florida's heat? +
Yes. Duramax diesels are engineered and tested for high-temperature towing, and they avoid the cold-start issues diesel owners face in northern climates. The main Florida-specific concern is moisture in fuel, so keeping up with fuel filter and water separator service is especially important for Sebring-area diesel owners.
What Sebring-Area Truck Owners Are Saying
The best diesel truck for sale in Sebring, FL is the one that matches the load you tow and the miles you drive — for most heavy haulers that means a Silverado HD Duramax, and for everyday drivers a Silverado 1500 with the 3.0L Duramax. Come see both at 1650 US HWY 27 South, Avon Park, FL 33825, call us at 888-511-2883, or start shopping anytime at hustonchevrolet.com.
