Peterbilt 354/355

The Peterbilt 354 and 355 were heavy-duty conventional trucks of the 1941 to 1949 Peterbilt line designed under founder T. A. Peterman. The list of Peterbilt vehicles groups them with the Model 364 in a single row, describes the group as heavy-duty trucks and dates it 1941 to 1949, and an Australian history of the marque calls the 354, 355 and 364 heavy-duty 6x4 trucks, meaning tandem rear-axle trucks, which fits the practice of the time of giving tandem-axle trucks numbers starting with 3. The Peterbilt article says the heavier-duty 364 was first developed for the logging industry in 1941 and then repurposed for military production in the Second World War, and the list adds that 28 Model 364s were built for the US Navy in 1942.
