Which year is the best? I beleive they discontinued the 5.9l in 2006, but I'm not sure. I don't drive a dodge, I drive fords mostly. I know this: A) Most dodge guys buy the truck because of the engine. B) The cummins is a great engine C) Interiors suck on ALL years D) Decent torque, MPG E) Automatic trans are NOT one of dodge's specialities. Sometime in late 10 I am going to be truck shopping. Due to recent decisions on my part, I can either buy a retired military m800 5 ton truck to tow around some heavy armor and get a toyota tacoma as a DD, or get a 2500/3500 series truck to do all with. Got some time to think it out though.
