Ford Super Duty trucks out-sell the heavy-duty pickups from Chevrolet and Dodge combined. Ford has improved them for 2003.
A new 6.0-liter diesel engine brings more power and reduced emissions to the Super Duty line. The standard 5.4-liter V8 gas engine has been revised for quieter and more refined operation. The base interior is nicer, and a power sliding moon roof is available for Crew Cabs. Those changes, plus new option packages make the 2003 F-350 and F-250 models more people-friendly.
Still, these trucks aren't designed to be family-sedan substitutes that make an occasional run to Home Depot. Ford's full-size but lighter-duty F-150 is more than enough truck for that job. The Super Duty pickups look like serious big rigs, and they are.
Ford Super Duty trucks are a bit long in the tooth, however, and do not offer the chassis sophistication of their counterparts from GM and Dodge, so they don't ride or handle as well. Their new and revised powertrains are first-class, however.
