I posted in the 2nd gen. section, but thought I would ask here. I have a 98 5.9 A/T 4x4 225k miles on it. I tow a 4200# gooseneck a lot. I haul 1-3 tons of firewood regularly. Considering an upgrade because I'm beating my old truck to death. Is there that much of a difference towing with say an 06 or 07 in the same truck style? I would like to stay with the 5.9, and a manual is not really on option because of health issues. Can't rely on left leg to push clutch sometimes. Thanks for your input.
