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.Click here to read more
