It was the industry's first full-size lightweight pickup truck with a full rear passenger compartment and 4 full-size doors, becoming the SuperCrew cab. Along with the Limited and Platinum, the King Ranch continues to comprise the luxury end of the F-150 spectrum. 40% of King Ranch F-150 sales are in Texas, Ford's largest pickup truck market. F-150 Platinum (2009–present) Introduced for 2009, Platinum is a luxury-oriented trim of the Ford F-150. Effectively replacing the Lincoln Mark LT in the United States and Canada (though its production continued through 2014 in Mexico), the Platinum adopted many of the luxury features and content from the Mark LT with more subdued exterior styling (the Platinum was fitted with an eggcrate grille similar to early models of the Ford Expedition). In 2013, Ford began use of the Platinum trim for Super Duty trucks, from the F-250 to the F-450 pickup trucks.
