I'm really close to pulling the trigger on an '06 Dodge reg. cab, cummins, 4x4, 4 spd auto, slt, 20k miles. Any thoughts on this truck good or bad? I've heard good things about the Cummins but have no idea if this year is good or bad historically. Anything you could tell me about it would be great. Were there 2 diesel engine options for that year because they are showing it at 305hp/555tq. I thought it was higher than that.
