The Chevrolet Silverado 1500 is a full-size, light-duty, half-ton pickup truck with heavy-duty 2500 and 3500 models augmenting the lineup for towing and hauling needs. Combined, Silverado is GM’s best-selling nameplate and usually takes second place in overall U.S. vehicle sales. Like most pickups, it’s available in various cab configurations, cargo bed lengths and trim levels, ranging from rubber-floored work trucks to premium models for the growing personal-use market. Engine choices have typically been a V-6 and at least two V-8s. The Silverado 1500 shares mechanical underpinnings with GM’s other half-ton pickup, the GMC Sierra 1500.
