2022 Peterbilt Trucks For Sale

The most common 2022 Peterbilt trucks on the used market usually include the 337, 348, 389, 567, and 579. The 337 is a popular medium-duty platform for rollback, box truck, and utility applications. The 348 and 567 are more vocational, often used for dump, mixer, crane, or severe-service work. The 579 is Peterbilt’s aerodynamic highway tractor, while the 389 remains a favorite for buyers who want a classic long-hood conventional with premium trim and owner-operator appeal.

Engine choice depends on the model and application. Medium-duty 2022 Peterbilt trucks commonly use the Cummins PX-7 or similar ratings suited for Class 6 and Class 7 work. Heavier vocational and highway models often use PACCAR MX or Cummins X15 engines, with horsepower and torque selected around payload, terrain, and duty cycle. Buyers should look beyond horsepower alone and check torque output, transmission pairing, rear axle ratio, and maintenance history to understand how the truck will perform in actual service.

On a vocational 2022 Peterbilt, focus on body integration and chassis match as much as the truck itself. Verify GVWR, front and rear axle ratings, suspension type, PTO configuration if equipped, frame condition, and wheelbase suitability for the body installed. If it is a rollback, wrecker, dump, or service truck, inspect hydraulic components, bed or body mounting, winches, wheel lifts, toolboxes, and electrical controls. A clean cab and low age are helpful, but the real value is in whether the chassis spec was built correctly for the equipment and job cycle.

Yes. A 2022 Peterbilt can fit either profile depending on the spec. Fleets often value Peterbilt for parts support, driver acceptance, and strong vocational and highway model coverage across multiple classes. Owner-operators often focus on cab comfort, resale strength, brand reputation, and appearance, especially in models like the 389 and well-equipped 579. The best fit comes down to operating cost, service access, and whether the truck’s wheelbase, axle setup, and drivetrain match the route and load profile.
