About Us

Laura, Jim, and Bob at the shop in Milford circa 1950.  The dog is Happy - the first field pup.

We've been at this location for over 80 years.

Beginning in the ’60s,  the family moved on from repair work to building their own flatbed trailers. A new idea formed to build mobile fuel trailers – The Field Pup. Originally, the concept was to make fuel tank carting for farmers. The dog in the picture is Happy, the first field pup.
