What Is a Dually Truck?by Matthew Suedkamp
Dually trucks are used for a wide variety of jobs, including construction and other commercial applications. They may be an added expense, but are often necessary depending on the work.
A "dually" truck is a pickup that has dual rear wheels on each side. These pickup trucks are fitted with heavy-duty brakes, heavy-duty shocks and heavy-duty springs. Furthermore, they often run the largest and most powerful engines that the manufacturer offers. These pickups are called "one-ton" pickups because of their ability to carry more than 2,000 lbs. in their beds and tow large trailers.
As of 2010, four different dually models are available in the market: Ford Super Duty F-350, Chevrolet Silverado 3500, GMC Sierra 3500 and the Dodge Ram 3500 Heavy Duty. All four trucks are available with gasoline and diesel engines, and come in varied cab configurations, including extended cabs and four-door models.
Heavy-duty dually trucks are usually used to tow very large trailers, such as horse trailers and fifth-wheel campers. Many of these trailers can weigh over 20,000 lbs. fully loaded. They are also used in construction to tow heavy machinery and materials, as well as workers to the job site. The flexibility of these trucks to complete a variety of different jobs makes them so useful.
