lisascs....One thing to consider is the 2wd. Ram from 2003 and newer is equiped with rack and pinion steering and 4wd. is not. I have driven both and the 2wd. feels more stable to me and and keeps a straighter line on the highway.
I would also seriously think about the 3500. It's not that much more money but has a considerably larger payload than the 2500.
I have a 2500 and am kicking myself for not originally getting the one ton. We are now looking at a larger TT or FW and are limited by weights. Oh well live and learn.
