Peterbilt ECM Programming
Peterbilt sits at the intersection of owner-operator pride and fleet operational reality. The 389 is the classic owner-operator long-haul tractor. The 579 has earned its place as a modern fleet long-haul standard. The vocational range — 567 severe-duty, 548 refuse cabover, 537 medium severe-duty, 535 city delivery, 520 refuse — covers the work where Peterbilt's durability matters.
