GMC – other models: the collective page of commercial vehicles outside the named ranges, from the CCKW military truck through the PD-4501 Scenicruiser touring coach to the Sierra pick-up, 58 to 303 kW
This page gathers the GMC commercial vehicles the register could not assign to a named range – from pick-ups of the Sierra and Suburban family through military trucks to a touring coach. GMC, the General Motors Truck Company, was formed in 1911/1912 from the merger of the Rapid Motor Vehicle Company and the Reliance Motor Car Company, and during the Second World War built with the CCKW the most numerous American military truck, known as the "Deuce and a Half". In the 1950s GMC's predecessor brand, Yellow Coach/GM, built the PD-4501 Scenicruiser touring coach for Greyhound, a double-deck long-distance vehicle. The Sierra pick-up range has shared its technical base with the Chevrolet Silverado since the 1980s, differing in trim and grille.

The register lists here 32 versions with 58 to 303 kW from six- to eight-cylinders of 3,270 to 12,060 cm³ displacement, unladen weights from 1,740 to 13,750 kg, gross weights from 12,258 to 31,941 kg, lengths from 5,100 to 12,000 mm and widths from 1,870 to 2,500 mm.
GMC commercial vehicles stand in North America for robust V8 engineering in the pick-up segment, while the historic military and bus models are found today chiefly with collectors and at classic-vehicle events.
On Sierra pick-ups, corrosion on the frame and bed, the condition of the automatic transmission and brakes, and on the historic military and bus models the completeness of original parts and the condition of the drivetrain and axles all count; spare parts for current models run through the GMC network, for historic vehicles through specialists.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
