What is the difference between an F-250 and an F-100?
Quick Answer
The F-100 is Ford's half-ton pickup and the F-250 is the three-quarter-ton, one weight class up. They share the same cab and styling, but the F-250 has heavier springs, axles, and brakes for towing and hauling, with a firmer ride. The F-150 later slotted between them.
The numbers are load ratings.
F-100 (half-ton)
The lighter, smoother-riding everyday pickup, the one most collectors picture.
F-250 (three-quarter-ton)
Same looks, stouter underpinnings: heavier springs, axles, and brakes for real work. It rides firmer but tows and hauls more. Many lived working lives, so inspect for hard use.
