As has been stated here by others, the 2003 2500 and 3500s are still going to be coil-sprung, solid axles.
I was upset about the 1500 going IFS for a bit as well, then the more I've wheeled, the more I've decided that the D44 front axle just doesn't cut it with a 5,000# truck. Great on a jeep, but not on something with 50% more mass.
The 1500s are mostly bought by people who don't use a truck for a truck. Unfortunate, but true. So IFS makes sense. And even for those who do use a truck as a truck, it's only Off-road that you really start to run into issues with IFS.
For light towing, and for 4-hi in the snow, IFS is fine. For plowing snow, hauling heavy loads, off-roading a 5-6,000# truck, you want something heavier duty than IFS. So you do what both Ford, and now Dodge have done, which is to put IFS on the 1500s that are mostly daily-drivers and "Hollywood" trucks that are never put into a position to get even scratched, let alone crossed-up on a trail, and use the 2500 and 3500s with the solid front axles for the heavy-duty stuff.
