Here is some info on the new trucks, thought people might want to know.
I pasted this from a few sites on ww.car-truck.com
The manual transmission line-up will include both a regular and HD version of the NV4500 five-speed. The regular version will be standard with the 5.7 HEMI and the 8-liter V10. The NV4500HD will be standard on the regular output 5.9 liter diesel. The HO diesel will come with the NV5600 6-speed.
Four-wheel-drive 2500/3500 Rams will be available with two new transfer cases the NV271 and the NV273. The new cases are quieter then the 241SD/241HD that they replace. The new cases are stiffer and use fewer pieces, they are designed to last 50% longer the current ones. They are capable of handling 40% more torque than the current cases. The two models are essentially identical, the only difference, the NV271 is a manually operated, the NV273 is electronically operated..
As far as towing goes, it will depend on how the truck is equipped. The Gross Combine Weight Ratings (is the maximum combined weight for the truck and trailer) will range from 15,000 lbs. for a 2wd 5.7 HEMI equipped Ram 2500 to 23,000 lbs. for a HO Cummins equipped dually 3500. Gross Trailer Weight Ratings (GTWR is the max allowable weight for a trailer and its cargo) range from 8,850 to 15,750 lbs. Gross Vehicle Weight ratings (GVW) are all higher for 2003. The 2wd trucks equipped with the 5.7 will be rated at 11,000 pounds, that kicks up to 11,500 in 4wd trucks. The 8-liter V10 will also be rated at 11,500. Cummins equipped Ram's will be rated at 12,500 lb. The 2500 will have a maximum payload of 3400 lbs. the 3500 will be able to carry 5590 lbs. (with the diesel).
The Engine lineup for the 2003 2500/3500 trucks when the debut in September of 2002 will be 5.7 liter HEMI, 8.0 liter V10 and 5.9 liter turbo diesel (in regular and high output). The V10 used in the new big rams is the same unit used in the current trucks. Dodge considered designing a new HEMI V10 but decided that the cost was prohibitive. The 6.1 liter V8 version of the new HEMI design will be available for the 2004 model year.
