Question: what is a 1 ton pickup?
Answer: The Chevrolet Silverado/GMC Sierra 3500, Ford F-350, and Ram 3500 are known as "one ton" pickups. Similar schemes exist for vans and SUVs (e.g. a 1-ton Dodge Van or a ​1⁄2-ton GMC Suburban), medium duty trucks (e.g. the 1​1⁄2-ton Ford F-450) and some military vehicles, like the ubiquitous deuce-and-a-half.
