This Ford medium-duty nameplate was the diesel-designated version of the company’s conventional F-Series commercial trucks. In Ford’s truck numbering system, the extra zero identified diesel-equipped versions of the heavier F-Series models, so the nameplate appeared alongside the gasoline F-series trucks rather than as a separate light-duty pickup line. It was part of the medium-duty Ford truck family that served vocational buyers such as dump-truck operators, municipal fleets, contractors, and other commercial users who needed a heavier chassis than the familiar F-100 through F-350 pickups.
The nameplate can be traced to the late 1960s model-year truck lineup and remained in Ford’s medium-duty literature through the 1970s and 1980s. During that era, it typically denoted a chassis-cab or conventional medium-duty truck configured with diesel power, while the corresponding gasoline trucks used the shorter F-series numbering. Ford’s commercial-truck books show the designation continuing into the 1988 model year, after which Ford’s medium-duty naming shifted away from the extra-zero format and back toward the simpler F-700/F-800 style designations for the next era of trucks.
Enthusiasts often remember this nameplate as part of Ford’s transition from the old simple truck numbering to the more complex medium- and heavy-duty naming conventions used in the 1970s and 1980s. It represents a distinct chapter in Ford truck history: a work-focused diesel variant of the conventional F-Series before Ford reorganized its medium-duty lineup in the late 1980s.
