Find Dodge Dealers in Cincinnati, Ohio

Whats up all? Im a long time edmunds TH member but rarely read the Pickups threads, so I would really appreciate any help you might offer. My cousin is interested in buying the above, a 2003 4.7L 1500 Crew Cab 4x4 with 24,000 miles. The asking price is $21,000. I am not sure about features or model specifics, but from what I've read, it sounds like your typical SLT, nothing fancy. For anyone who has the time, what are the problem areas that should be paid particular attention to with this truck? It is being sold by a private owner who is looking for something smaller and less consumptive of fuel. If this car carried Chryslers extended powertrain warranty as a new vehicle, does that transfer to subsequent owners? I know the Dakota is due for a redesign... but since my cousin really only requires a 6ft bed and "better than jump seats", would a discounted but reasonably priced new Dakota be a better choice? Thanks very much. ~alpha
