Pierce Manufacturing history

Here's a throwback from Mike Summa for #TBT:

For TBT. The Pierce Suburban on the Ford C chassis was a common sight in our area. These trucks were reliable and well-liked by firefighters. Take a look, enjoy the nostalgia, and feel free to share your memories or thoughts below.

These photos give a nice glimpse into the past—those old fire apparatus had a unique charm that modern rigs don’t always have. Whether you were a firefighter back then or just grew up watching these trucks roll by, there’s something special about them. If you have any stories or memories related to the Pierce Suburban, we’d love to hear them!
