The Peterbilt 379 is a legendary truck that has captured the hearts of truck enthusiasts worldwide. As a model line of Class 8 trucks produced by the Peterbilt division of PACCAR from 1987 to 2007, the 379 was a conventional-cab truck configured primarily for highway use, serving as the flagship of the Peterbilt model line.

It was the successor to the 359 and was designed to be a truck for the owner-operator market.

The 379 was a true classic in every sense of the word. It was a truck that was designed to be both powerful and stylish, with a look that was unmistakably Peterbilt. The truck was known for its long hood, which housed a powerful engine that could haul even the heaviest loads.

It was also known for its comfortable interior, which made it a favorite among truck drivers who spent long hours on the road.

The truck was available in a variety of configurations, including day cab, sleeper cab, and extended hood models.
