Peterbilt Model 548

The medium-duty Peterbilt Model 548 is the ultimate in durability, versatility and productivity. As versatile as it is tough, the Model 548 accommodates many configurations with a wide range of options for roof height, hood length and suspension. Designed to handle heavier vocational jobs, the Model 548 is a rugged workhorse with cab accommodations for up to three passengers.

The Model 548 truck is built for the big jobs with a GVWR up to 66,000 lbs. Its rugged construction includes an all-aluminum, corrosion-resistant cab with newly engineered hood and chassis components for added strength and durability. The quiet, comfortable cab and customizable dash design provide an unrivaled driving experience. And PACCAR’s TX-8 automatic transmission delivers a best-in-class power-to-weight ratio, with up to 5% fuel savings compared to other competitive transmissions. The Model 548 comes with the option for a PACCAR PX-7 or PX-9, as well as a Cummins L9N natural gas engine.
