SLV meaning in General ?

The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.

The Chevrolet Silverado shares mechanical commonality with the GMC Sierra; GMC ended the use of the C/K nomenclature a model generation prior to Chevrolet. In Mexico, heavy-duty versions of the Silverado use the Chevrolet Cheyenne name. Competing against the Ford F-Series, Dodge Ram, Nissan Titan, and Toyota Tundra, the Silverado is among the best-selling vehicles in the United States, selling almost 12 million examples since its introduction.
