My 2006 Cummins MegaCab is putting out about 900 ft/lbs at the shaft, and I'm still on transmission #1.
Find a 2006 or 2007 (Make sure it's a 5.9). There are plenty of clean, used Cummins Dodges around for a reasonable price. If you're worried about the transmission, spend a few extra $$ and get a Goering or ATS. You'll still be money ahead and NO pollution control crap.
Here's a bunch of listings within 200 miles of your town:
