Quick answer: The used Peterbilt models with the strongest reputation for long service life are the 379, 389, 367, 567 and 579. The 379 (built from 1986 to 2007) and the 389 that replaced it are the long-nose highway classics. The 367 and 567 are the vocational trucks for dump, heavy haul and severe service work. The 579 is the aerodynamic highway tractor launched in 2012. No model is durable on its badge alone. Maintenance records, an independent inspection with an ECM scan, and a spec that matches your work decide whether a used Peterbilt will last, and they also shape how lenders look at the file.
Key takeaways
- Peterbilt built over 230,000 Model 379s between 1986 and 2007, so parts and mechanics who know them are easy to find (FleetOwner, April 2007).
- The 389 replaced the 379 and was announced in March 2006. Peterbilt named the Model 589 as its successor, with production starting January 2024.
- The 367 arrived in early 2007 as a vocational truck with a heavy-haul option. The 567 was unveiled in March 2013 for severe-service work.
- The 579 was unveiled in March 2012 with an aluminum cab and standard electronic stability control.
- In Canada, trucks with a model year before 2000 are exempt from the federal ELD rule. Trucks from 2000 on are covered even with an older engine.
- Age, kilometres and paperwork affect financing terms on older units. Startups usually need at least 6 months of revenue in business bank statements.
What makes a used Peterbilt durable?
Peterbilt is a PACCAR brand that builds its Class 8 trucks in Denton, Texas. Its long-nose models have a loyal following among owner-operators, and that loyalty helps resale. Trucks that owners care about tend to get serviced on time, and a well-kept truck holds value.
Durability on a used truck comes from three things more than the brand:
- How the truck was specced when new: engine, transmission, axle ratings and frame for the job it did.
- How it was maintained: oil analysis, scheduled service, emissions system care and any overhaul work.
- What work it did: steady highway kilometres are easier on a driveline than stop-and-start vocational work with heavy PTO use.
Two trucks of the same model and year can be worth very different amounts because of those factors. For a broader look at the brand, see our used Peterbilt buying guide.
The five used Peterbilt models at a glance
| Model | Type | Production (approx.) | Typical use | Main thing to check |
|---|---|---|---|---|
| 379 | Long-nose conventional | 1986 to 2007 | Highway, heavy haul, show trucks | Frame, wiring, engine overhaul history |
| 389 | Long-nose conventional | 2007 to early 2024 | Highway, owner-operator, heavy haul | Emissions system records |
| 367 | Vocational | 2007 onward | Dump, logging, oilfield, heavy haul | Engine hours, PTO use, suspension |
| 567 | Vocational | 2013 onward | Construction, mixer, severe service | Hours vs kilometres, body mounting |
| 579 | Aerodynamic highway tractor | 2012 onward | Fleet linehaul, regional | Software updates, aftertreatment |
Production years come from Peterbilt and trade press announcements listed in our sources. Model years on the road can differ slightly from announcement dates.
1. Peterbilt 379: the long-running classic
The 379 ran for about 20 years, and Peterbilt built more than 230,000 of them, according to FleetOwner's April 2007 report on the final unit. That volume helps it sell today: parts are around, aftermarket support is deep, and many shops know the truck well.
Many 379s predate the diesel particulate filter and DEF systems that arrived on later engines. Some buyers like that simpler setup. The trade-off is age. The newest 379s are now close to 20 years old.
What to inspect on a 379
- Frame rails and crossmembers for cracks, rust and old weld repairs.
- Wiring harnesses, which can get brittle or patched over decades.
- Proof of any in-frame or out-of-frame engine overhaul, with dates and kilometres.
- Cab mounts, doors and hinges, which wear on high-kilometre units.
In Canada, the federal ELD rule exempts vehicles manufactured before 2000, according to Manitoba Transportation and Infrastructure. A 2000 or later truck is not exempt, even with a pre-2000 engine swapped in. That matters if you plan to run a late 379 across provincial lines.
2. Peterbilt 389: the 379's replacement
Peterbilt announced the 389 in March 2006 as the replacement for the flagship 379, with new models slated for early 2007 (Equipment World, March 22, 2006). It kept the classic look and added aerodynamic touches such as reshaped bumpers and fairings.
In 2023, Peterbilt introduced the Model 589 and positioned it as the 389's successor. Its press release says 589 production began in January 2024 at the Denton plant. So the 389 is now a used-only truck, and well-kept late units are in steady demand.
What to inspect on a 389
- DPF, DEF and EGR service records. Ask for cleaning and replacement dates.
- ECM data: fault codes, idle time and any sign the emissions system was tampered with.
- Engine make and model. Units were built with different engines, which affects parts and shop choices.
- Driveline matching for your loads, including rear axle ratio and transmission.
A truck with deleted emissions equipment can create legal and resale problems. Our article on emissions standards in Canada's trucking industry explains why buyers should walk away from tampered units.
3. Peterbilt 367: the vocational all-rounder
The 367 was part of the same March 2006 product launch. Equipment World reported that it came with a heavy-haul configuration and a high-capacity cooling system for high-horsepower engines. Set-forward and set-back front axle options let it work as a dump truck, logging truck or heavy-haul tractor.
Vocational trucks usually run fewer kilometres than highway tractors but work harder per kilometre. Low kilometres on a 367 can hide many hours of idling or PTO work.
What to inspect on a 367
- Engine hours compared with kilometres. High hours with low kilometres point to heavy idling or PTO use.
- Suspension, springs and axle housings for overload damage.
- Frame condition under the body, where mounts can crack.
- Hydraulics, PTO and any body equipment, which may need their own inspection.
For a dump body or a wet kit, see our dump truck financing page and the vocational and service trucks section.
4. Peterbilt 567: the severe-service specialist
Peterbilt unveiled the 567 at the Mid-America Trucking Show in March 2013, with production planned for June that year (FleetOwner, March 20, 2013). It came in two hood lengths, as a day cab or with a sleeper, and with single, tandem or tridem drive axles.
FleetOwner listed a reinforced aluminum cab, front air disc brakes and standard electronic stability control. Steering changes cut the turning diameter by up to 9 feet, which helps on tight job sites. Launch engines included the PACCAR MX-13, with a Cummins 12-litre as an option.
What to inspect on a 567
- Hours, idle percentage and PTO hours from the ECM report.
- Front axle and steering components, especially on set-back axle trucks.
- Body mounting and any mixer, dump or crane equipment.
- Service records from the previous owner's fleet, if it came from one.
5. Peterbilt 579: the aerodynamic highway tractor
The 579 was unveiled in Louisville in March 2012 (Heavy Duty Trucking, March 22, 2012). It brought an 83-inch-wide aluminum cab, a panoramic windshield and modular aero packages aimed at the EPA SmartWay designation. Front air disc brakes and electronic stability control came standard.
The 579 is common in fleets, so the used market has plenty of units, often with fleet maintenance records. Fleet trucks also tend to run high kilometres, so check the engine and aftertreatment carefully.
What to inspect on a 579
- Software and ECM updates, plus any open recalls.
- Aftertreatment history: DPF cleanings, DEF doser and sensor replacements.
- Automated transmission behaviour on a test drive.
- Sleeper and HVAC condition on sleeper units.
Inspection checklist for any used Peterbilt
The same checks apply to every model. Our post on used semi truck buying mistakes covers the costly ones in more detail.
| Check | What to ask for | Why it matters |
|---|---|---|
| Maintenance records | Service invoices, oil analysis, overhaul paperwork | Shows how the truck was cared for |
| Independent inspection | Heavy-duty mechanic, not the seller's shop | Finds problems before you own them |
| ECM report | Hours, idle time, fault codes, PTO hours | Shows real usage beyond the odometer |
| Emissions system | DPF, DEF and EGR history, no tampering | Avoids compliance and repair costs |
| Lien search | Provincial personal property registry search | Confirms the seller owns it free and clear |
| Safety certificate | Valid provincial safety inspection | Needed to plate and insure the truck |

How Peterbilt compares with other brands
Peterbilt usually sells at a premium to similar-age trucks from some other brands, mostly because of its styling and owner demand. Whether that premium makes sense depends on your work and your resale plans. These comparisons help:

Financing a used Peterbilt in Canada
Lenders look at the truck and at you. On the truck side, age, kilometres, condition and the seller (dealer or private) all affect terms. On your side, they look at credit, time in business, cash flow and down payment.
The main options are:
- An equipment loan for trucks and trailers, where you own the truck from day one.
- A lease, which can lower the upfront cost and suits fleets that rotate units.
- Refinancing or a sale-leaseback to free up equity in a truck you already own.
Older trucks such as a 379 often get shorter terms, or a lender may want a larger down payment. Our Peterbilt truck financing guide for Canada goes deeper, and the best trucks for owner-operators in Canada can help you shortlist.
What we see on real files
A few patterns come up often on used Peterbilt files. Private sales with a full stack of service invoices move faster than dealer units with no history. Older long-nose trucks get more questions from lenders about the inspection report and the age of major components. Vocational trucks get asked about hours, and sometimes about the body equipment. Buyers who line up the inspection and lien search before applying usually save a week or more. Newer businesses can qualify when they show at least 6 months of revenue in their business bank statements.
Frequently asked questions
Which used Peterbilt lasts the longest?
No single model always wins. A well-maintained 379, 389 or 579 can stay in service a long time. Records and inspection results tell you more than the model number.
When did Peterbilt stop making the 379?
The final 379 was delivered in 2007, after a run that started in 1986. Peterbilt built more than 230,000 of them, according to FleetOwner.
Is the Peterbilt 389 still made?
Peterbilt named the Model 589 as the 389's successor, with production starting in January 2024. New buyers now get the 589, so the 389 is bought used.
Does an older 379 need an ELD in Canada?
Vehicles manufactured before 2000 are exempt from the federal ELD rule. A truck from 2000 or later must comply, even with an older engine. Check your province's guidance.
Can I finance a 15-year-old Peterbilt?
Often, yes, though terms depend on the truck's condition, the seller and your file. Expect lenders to ask for an inspection and possibly a larger down payment.
567 or 367 for dump work?
Both are built for vocational work. The 567 is the newer design with more modern safety features. A clean 367 can cost less. Compare hours and condition rather than model alone.
