A Bit of Backstory (For Context)

Peterbilt started in 1939 on the U.S. West Coast and later shifted its main operations to Denton, Texas, as older plants in California and Tennessee were phased out. Over time, PACCAR built and modernized facilities in Canada and Mexico to handle medium‑duty and region‑specific production, especially for the Canadian market.

Today, when you see a Peterbilt on the road, it was almost certainly built in one of these three plants, with Denton still being the flagship hub.
