My $.02...... we went to a new 2010 Ram 3500 4x4 megacab CTD SRW six years ago from a 1989 Chevy 3500 4x4 crewcab dually with a 454. As said by others, I will never tow with a gas engine again. If a 2500 Ram CTD is on the table then a like equipped 3500 is only a little more and has a lot higher cargo capacity. In our case a 2500 base price was $39760 and CTD option was $7500. The same level 3500 with standard CTD was $47120 minus $990 for dually delete credit. Do the math. We did not get TPMS (not available on 3500) but just added TST 507 for TV and FW last year.
