Introduced in 1998 as a ’99 model, the Ford Super Duty pickup series has led the heavy-duty segment, utilizing a dedicated HD platform that has achieved best-in-class trailer tow ratings and payload. Whereas competitors to date have modified existing light-duty platforms, Ford has gone the dual architecture route, dominating this division in sales and contributing to the F-Series’ status as the best-selling pickup in America for 30 years straight. For the 2008 model year, Ford has added the F-450 Super Duty to the lineup.
