dualie
n.— «A dualie has six tires, two each per rear wheel covered in huge flared fenders behind a four-door cab that can easily swallow five large cowboys or construction workers without starting a fist fight. My wife likens it to a large family car with a huge box attached behind, and she’s right.» —“Big & Bad Ford F-350 is dualie for duties” by Dan Scanlan Florida Times-Union (Jacksonville) Jan. 30, 1999.
