The short answer
A used Chevrolet Silverado 2500HD or 3500HD can be CarBravo certified at Swant Graber Motors if it's under 10 model years and 100,000 miles and passes GM's 126-point inspection. A certified truck comes with a 12-month/12,000-mile Bumper-to-Bumper Limited Warranty and GM's 10-day/500-mile Vehicle Exchange (an exchange, not a refund; GM's limits apply). CarBravo also says GM requires dealers to complete all open safety recalls before a CarBravo vehicle is listed or sold.
For choosing the truck itself, four decisions cover most of it: gas or Duramax, 2500HD or 3500HD, which generation, and condition. Condition usually matters more than the model year.
Used Silverado HD by generation (verified)
| Model years | Gas engine and transmission | Duramax diesel and transmission | Notes |
|---|---|---|---|
| 2017–2019 | 6.0L V8, 6-speed automatic | 6.6L Duramax (L5P), 445 hp / 910 lb-ft, Allison 6-speed | Previous body style; check the window sticker for exact ratings |
| 2020–2023 | 6.6L V8 (L8T), 401 hp / 464 lb-ft, 6-speed automatic | 6.6L Duramax, 445 hp / 910 lb-ft, Allison 10-speed | All-new truck: longer wheelbase on Crew Cab, larger cab, max tow up to 35,500 lb (3500HD DRW, gooseneck, diesel). Trims: Work Truck, Custom, LT, LTZ, High Country |
| 2024–2026 | 6.6L V8, 401 hp / 464 lb-ft, Allison 10-speed | 6.6L Duramax, 470 hp / 975 lb-ft, Allison 10-speed | Refresh: 13.4-inch screen on LT and up, new trailering tech, ZR2 added, max tow up to 36,000 lb (3500HD DRW) |
| 2027 | 6.6L V8, 412 hp / 472 lb-ft | All-new 8.3L Duramax V8, 555 hp / 1,230 lb-ft | New-truck only for now; see the Silverado HD hub |
2017–2019 gas output comes from GM's 2020 product guide, which says the new 6.6L gas engine has 11% more horsepower and 22% more torque than the 6.0L it replaced. The 6.0L's exact rating varied, so check the window sticker. Towing and payload depend on cab, bed, axle, drivetrain and SRW or DRW, so use the door-jamb label and the original window sticker for the specific truck. We can pull both from the VIN.
What changed year to year, in plain terms
- 2020: the biggest change. The truck was all new, with the 6.6L gas V8 and a 10-speed Allison behind the Duramax. GM added up to 15 available camera views (some need an accessory camera), an easier-to-reach block-heater cord outlet in the front bumper and a DEF fill inside the fuel door.
- 2024: the gas engine also got the Allison 10-speed (GM says gas GCWR rose to 26,000 lb). Duramax output rose to 470 hp / 975 lb-ft. LT and up got the new interior with a 13.4-inch screen, and the ZR2 joined the lineup.
- Earlier trucks (2017–2019): simpler interiors and fewer camera options. They're often lower priced, which suits buyers who mostly need a plow truck or a work truck.
Used gas vs. Duramax: how buyers usually decide
- 6.0L or 6.6L gas: lower purchase price, no DEF and simpler emissions hardware. Common for plowing, short hauls and lighter trailers. A 2024+ gas truck gets the 10-speed too.
- 6.6L Duramax: the torque and tow ratings heavy fifth-wheel owners look for, plus the exhaust brake on long grades. Budget for DEF, fuel filters and emissions-system upkeep as the truck ages.
- Mostly short trips and idling? Many mechanics suggest gas, because diesel emissions systems do best with regular longer runs. That's general guidance, not a rule.
- Go deeper: Duramax vs 6.6L gas · towing and payload.
2500HD or 3500HD used?
The 3500HD adds payload and is offered with dual rear wheels (DRW), which carry the lineup's highest gooseneck ratings. The 2500HD rides a bit easier empty and is usually easier to find used. If a fifth-wheel's pin weight plus passengers and gear gets close to a 2500HD's door-jamb payload, a 3500HD gives more margin. Side by side: 2500HD vs 3500HD.
Trims you'll see on used trucks
| Trim | Who usually buys it |
|---|---|
| Work Truck | Fleets, farms and plow trucks; vinyl floors and basic equipment |
| Custom | Value buyers who want body-color trim and nicer wheels |
| LT | The most common used trim; more comfort and tech |
| LTZ | Leather and more driver-assist features |
| High Country | Top luxury trim |
| ZR2 (2024+) | Off-road suspension and tires; check payload, which is lower than other trims |
Equipment varies by year and option package, so check the window sticker for exactly what a truck has. Trims and packages: Silverado HD trims explained · ZR2.
Recalls by model year (NHTSA)
NHTSA lists 26 distinct safety-recall campaigns that cover at least one 2017–2025 Silverado 2500HD/3500HD model year (as of Oct. 11, 2026). 2020, the first year of the new generation, has the most (10). A recall count is not a reliability score.
| Model year | Campaigns | Components named most |
|---|---|---|
| 2017 | 6 | Seat belts, Engine, Air bags |
| 2018 | 6 | Seat belts, Engine, Equipment |
| 2019 | 7 | Air bags (4), Equipment, Engine |
| 2020 | 10 | Powertrain (3), Latches and locks (2), Seat belts (2) |
| 2021 | 6 | Seat belts (2), Tires, Hydraulic brakes |
| 2022 | 3 | Hydraulic brakes, Latches and locks, Powertrain |
| 2023 | 1 | Latches and locks |
| 2024 | 4 | Latches and locks (2), Steering, Tires |
| 2025 | 2 | Tires, Fuel system (gas) |
Campaigns that cover the most years
| Campaign | Component | Years | What NHTSA says could happen |
|---|---|---|---|
| 24V060000 | Latches and locks | 2020–2024 | An unlatched tailgate may open while driving and cause a loss of cargo. |
| 19V328000 | Engine | 2017–2019 | A short circuit may damage engine components and increase fire risk. |
| 21V496000 | Equipment | 2017–2019 | An electrical short circuit can increase the risk of fire. |
| 23V047000 | Fuel system (diesel) | 2017–2019 | An engine stall increases the risk of a crash. |
| 24V797000 | Powertrain | 2020–2022 | Rear wheel lock-up can increase the risk of a crash. |
| 20V792000 | Seat belts | 2020–2021 | The front-center seat belt may not restrain properly if a bracket isn't secured. |
Park-outside warning: 21V758000 (hydraulic brakes, 2021–2022). NHTSA says water in the brake modulator may cause a short circuit and fire risk. Confirm this one is done before you take a truck home.
Filed in 2026 (a truck checked last year may need a fresh look): 26V530000 tires, 2024–2025; 26V325000 and 26V166000 air bags, 2019; 26V129000 fuel system, 2025; 26V083000 powertrain, 2020.
Full detail and how to check a VIN: used Silverado HD recalls by year.
Setting a budget for a used heavy-duty truck
Heavy-duty pickups hold their value, so a used one isn't always a bargain compared with new. It helps to build the budget around the whole cost of owning one, not just the sticker price.
- Price and fees. Ask for an itemized out-the-door quote. Our only dealer fee is the $127.50 documentation fee; tax, title and registration are set by the state.
- Registration weight. Wisconsin registers many heavy-duty pickups by gross weight. Check the fee for the truck's GVWR with the Wisconsin DMV before you settle on a 3500 or a dually.
- Insurance. Get a quote on the actual VIN. Premiums vary a lot by trim, diesel or gas, and how you'll use it.
- Tires. HD load-range tires, and six of them on a dually, cost more than half-ton tires. Check tread depth and date codes on the test drive.
- Diesel extras. DEF, fuel filters and the larger oil capacity add to routine maintenance cost. Plan on it rather than being surprised.
- Protection. If you finance, GAP coverage covers the difference between what you owe and what insurance pays if the truck is totaled. A service contract is another option to price out. Both are optional.
Matching a used truck to your trailer
Heavy-duty ratings swing a lot between configurations, so the brochure maximum rarely applies to the truck in front of you. Here's how to check the numbers on the actual truck:
- Payload: the yellow Tire and Loading Information label on the driver's door jamb gives the weight of occupants and cargo the truck can carry. A fifth-wheel or gooseneck's pin weight, the hitch itself, passengers and gear all count against it.
- GVWR and GCWR: the certification label lists the gross vehicle weight rating. The combined rating (truck plus trailer) is on the original window sticker or in the trailering guide for that model year.
- Axle ratio and engine: these change the tow rating more than most people expect. The VIN and the build sheet show both, and we can decode them.
- A rough rule many RV dealers use: fifth-wheel pin weight often runs around 15–25% of the loaded trailer weight. Use the trailer's actual scale weight if you have it.
- Weigh it: when you're close to a limit, a trip across a certified truck scale with the trailer hooked up tells you more than any spec sheet.
If you're on the line between a 2500 and a 3500, most buyers go up a size. That gives more payload margin for a heavy hitch and gear.
Reading the history: records, use and modifications
- Vehicle history report: look at the number of owners, where it was registered, accident or damage reports and odometer readings. A report can miss things, so treat it as one input.
- Fleet, farm or personal: fleet and farm trucks often have regular service records. Their idle hours and work history can be harder on parts than the miles suggest. Many diesels show engine hours in the cluster, so ask to see them.
- Hitches and plows: a gooseneck ball in the bed, fifth-wheel rails, a plow mount or plow-harness wiring tells you how the truck was used. A truck that did that work isn't automatically bad. It just tells you which parts to look at.
- Lifts, wheels and tuners: lift kits and oversized tires change handling and wear. On a diesel, any sign of removed or modified emissions equipment is a serious concern: it can affect legality, warranty and resale. We won't overlook it.
- Paperwork: Wisconsin dealers disclose a used vehicle's condition on the Wisconsin Buyers Guide (Trans 139.04) posted on the window. Ask for it and read it together with the recall printout.
Used heavy-duty truck checklist
These are general, widely shared used-truck checks — not a verdict on any one truck. A heavy-duty pickup's history matters more than its model year, so we'd rather show you the records than make promises.
- Run the VIN for open recalls at nhtsa.gov/recalls. Recall repairs are free at a franchised dealer of that brand.
- Ask for service records. On diesels, look for regular oil, fuel-filter and DEF-system service; on gas engines, oil and transmission fluid intervals that match severe-duty use if it towed.
- Look at how it was used. A worn fifth-wheel/gooseneck hitch, plow mounts, aftermarket lift or tuner signs aren't automatically bad, but they tell you to look closer. Modified emissions equipment on a diesel is a red flag we won't overlook.
- Cold start it. Listen for rough running, check for warning lights and watch for excessive smoke on a diesel once warm.
- Check the hitch, wiring and brake controller — test trailer lights and the integrated brake controller if you plan to tow.
- Drive it loaded if you can, or at least on the highway: smooth shifts, straight tracking, no driveline clunks.
- Get an independent pre-purchase inspection if you're buying a non-certified truck. We're happy to have one done or let your mechanic look.
Rust and winter: northwest Wisconsin checks
Road salt is part of life in Barron County, so underbody condition varies a lot from truck to truck — two of the same year can look very different underneath. What many inspectors suggest checking (results vary; this isn't a guarantee of any truck's condition):
- Frame rails, crossmembers and spring hangers — surface rust is common; flaking, scaling or holes are not something to shrug off.
- Brake and fuel lines, rocker panels, cab corners, wheel wells and bed supports.
- Plow trucks: front-end parts, frame near the mount, and the electrical connections.
- Block heater cord and function on diesels — most owners here plug in on the coldest nights. Diesel fuel should be winter-blended; see our winter diesel notes.
- Battery health (diesels often run two batteries) and glow plug/grid heater operation on cold starts.
A test drive that tells you something
- Start it cold if you can, ideally after it sits overnight. Watch for warning lights and listen for rough idle.
- Cycle 4WD high and low on a gravel lot. Engagement should be quick and the light should come on and off cleanly.
- On the highway, check for straight tracking, steering play, wheel shimmy over bumps and smooth, prompt shifts.
- Test the exhaust brake or tow/haul mode on a downhill if it's equipped.
- Test every camera view, the trailer brake controller readout, the power mirrors and the upfitter switches if it has them.
- Afterward, look under the truck for fresh drips and smell for coolant or burning oil.

A private sale can cost less up front. A dealer or certified truck adds inspection, paperwork and some coverage. Which one is right depends on how much risk you're comfortable with. See CarBravo certified at Swant Graber.
Trade-in, financing and business use
- Trade-in: bring the title or payoff information, both keys and any service records. Records and a clean history often help the appraisal.
- Financing: get pre-approved online to see your terms before you shop. Longer terms lower the payment but raise the total interest.
- Business use: many heavy-duty pickups are over 6,000 lb GVWR, which is a threshold in some federal tax rules for business vehicles. This isn't tax advice. Talk with your tax professional about your situation.

Questions buyers ask
Can a used Silverado HD be CarBravo certified?
Yes, if it's under 10 model years and 100,000 miles and passes the 126-point inspection. It then carries a 12-month/12,000-mile Bumper-to-Bumper Limited Warranty.
Which used Silverado HD year is best?
There's no single best year. Many buyers look at 2020+ for the larger cab and the Allison 10-speed behind the Duramax, or 2024+ for the 10-speed on gas trucks and the newer interior. Condition and records usually matter more than the year.
When did the gas Silverado HD get the 10-speed?
For the 2024 model year, per Chevrolet. The 2020–2023 6.6L gas trucks use a 6-speed automatic.
What's the Duramax rating on a used Silverado HD?
445 hp / 910 lb-ft on 2017–2023 trucks and 470 hp / 975 lb-ft from 2024, per GM. The 2027 truck moves to a new 8.3L Duramax.
Used diesel or gas Silverado HD?
Diesel suits heavy, frequent towing. Gas suits plowing, lighter loads and short trips at a lower cost of entry. Match the truck's rating to your trailer.
Are recall repairs free on a used Silverado HD?
Yes. Safety-recall repairs are free at a franchised Chevrolet dealer regardless of who owns the truck. Check the VIN at nhtsa.gov/recalls.
Does a high recall count mean a truck is unreliable?
Not on its own. Campaigns range from software updates to large fixes and cover very different numbers of trucks. What matters is whether this VIN's recalls are done.
Do heavy-duty pickups have EPA MPG ratings?
No. They're above the weight class EPA rates, so there's no window-sticker MPG. Real-world mileage depends heavily on load, terrain and winter.
How many miles is too many on a used diesel?
There's no single cutoff. Service records, how the truck was used and an inspection tell you more than the odometer.
Should I get a pre-purchase inspection on a used truck?
On a non-certified truck, many buyers do. We're happy to have one done or to let your mechanic look at a truck from our lot.
What should I check for rust on a used truck in Wisconsin?
Frame rails, brake and fuel lines, rockers, cab corners, wheel wells and bed supports. Surface rust is common; scaling or holes deserve an inspector's look.
Do I need to plug in a diesel in Wisconsin winters?
Many owners plug in the block heater on the coldest nights. Check that the cord and heater work on a used truck, and use winter-blended fuel.
What should I bring to trade in my current truck?
The title or payoff information, all keys, and any service records you have.
