Peterbilt Model 379
Successor to the legendary 359, the 379 updated the classic long-nose formula with a wider cab, improved aerodynamics, and modern engine compatibility including the 600-hp Cummins N14. Owner-operators loved the 379 for its resale value, serviceability, and the pride of ownership it commanded among professional truckers.
