Mack Trucks B-Series
The Mack B-Series was the most successful Mack design of the 1950s and 60s — over 127,000 built across 13 years. Its distinctive Bulldog hood ornament, Mack END673 Thermodyne diesel, and virtually indestructible construction made it the first choice for construction, refuse, and logging operations.
