They offered a wide range of options for both work and leisure, accommodating various configurations, from basic work trucks to luxurious crew cabs. Under the hood, these F-Series models boasted a selection of powerful engines, including the 4.9L inline-six, the 5.0L V8, and the 5.8L V8 for gasoline options, along with the 6.9L and 7.3L diesel V8s for those seeking increased towing capacity and fuel economy.
