GMC Sierra – light-duty 1500-class pickup for everyday commercial use: six- and eight-cylinder engines from 97 to 216.9 kW, up to 3.5 t gross weight, double cab up to 6,130 mm long
The GMC Sierra has been GMC's standalone pickup range within General Motors since 1999, closely related in use to the Chevrolet Silverado, built at, among other plants, Fort Wayne (Indiana), Flint (Michigan) and Silao (Mexico); earlier generations already carried the Sierra name on the GMC C/K chassis from the 1980s. The base 1500 class, with roughly a tonne of payload, forms the volume model, while trim lines such as SLE, SLT, Elevation and Denali order comfort and appearance.

The register lists 65 versions here with 97 to 216.9 kW from six- and eight-cylinder engines of 2,999 to 7,440 cm³, unladen weights of 1,640 to 3,198 kg, gross vehicle weights of 2,359 to 3,500 kg, lengths of 5,020 to 6,130 mm and widths of 1,900 to 2,430 mm.
As a double-cab with an open load bed, the Sierra 1500 in North America serves both as a company vehicle for trades and services and as a private everyday vehicle; its main rivals are the Ford F-150, Ram 1500 and Toyota Tundra, against which GMC differentiates itself chiefly through equipment and the Denali luxury line.
When buying used, check frame corrosion at the rear leaf-spring mounts and around the load bed, cylinder deactivation condition and oil consumption on the petrol V8s, the transfer case and axle differentials on four-wheel-drive versions, and wear on the tow hitch on commercially used vehicles; parts are widely available through the GMC and GM parts network.
