GMC Pick-up: the collection page for the classic GMC flatbed trucks, half-ton class and Hydra-Matic automatic, six- and eight-cylinder engines
This collection page holds the register's classic pick-up models from GMC, General Motors' commercial vehicle brand, which has built trucks and pick-ups since the 1910s on shared engineering with Chevrolet while remaining a separate marque. Designations such as "1/2 Ton" and the three-digit number 100 denote the payload class, "4X4" four-wheel drive, "Hydra-Matic" GM's early 1950s automatic transmission technology, and "Step Side" the narrow bed with external fenders as opposed to the smooth Fleetside bed; "Silverado" and "Commercial" mark upper and purely utilitarian trim respectively.

The register lists 17 versions here with 3,540 to 5,180 cm³ displacement from six- and eight-cylinder engines, weights of 1,450 to 2,240 kg, gross vehicle weights of 1,870 to 3,500 kg, a length around 5,300 mm and widths of 1,850 to 2,100 mm.
As the practically identical counterpart to the Chevrolet pick-ups, GMC traditionally served more commercial and municipal buyers, as well as customers who valued a slightly more upmarket positioning; the pick-ups competed with the contemporary Ford F-Series and its Dodge equivalent.
On a used example, rust on the frame, sills and load bed matters most — a well-known weak point of the classic GM full-size pick-ups — along with the condition of the inline-six or V8 and its carburettor on older model years, the drum brakes and the rear leaf springs under load.
