Last year, Ford, Fiat-Chrysler and General Motors combined sold more than 2.2 million full-size trucks, controlling 93 percent of the segment.

Big pickup truck sales are important to automakers, which make huge profits on them. Sales rose nearly 6 percent last year to almost 2.4 million, even though total U.S. auto sales dropped 2 percent.

One in every seven vehicles sold last year was a big pickup, up from one in every nine in 2009 in the midst of the Great Recession. Ford’s F-Series pickup is the country’s top-selling vehicle, followed by the GM’s Chevy Silverado and Fiat-Chrysler’s Ram.
