Hello I'm new, looking for my first dodge diesel. My research has lead me to believe I want a 1998 12v. 4x4 quad cab, auto trans. The prices are varying a lot. Don't know what I should be paying, anyone have a suggestion? Then I found a 2004 today that's stock with 192k miles for 15k. How are the transmissions in that yr. I've heard conflicting stories. What should I be aware of for problems? It's the 5.9
