Tim, From what Ive seen and what my truck cost, you should be able to buy that truck NEW for not much more than the price they are asking used. Try Tommygun or Big Bob. My 98 came from Dave Smith and my 04. 5 came from Lithia. the 04. 4 was right at the high $32k out the door fully loaded 3500 4x4 Quad cab Swb automatic. Then you will have a NEW truck that no one else has messed with and you will never have to wonder why someone sold it so soon with such low mileage. (wrecked, lemmon, trud) Just a thought. Call around and save some money! You then can also get the options you really want and not what the guy before you wanted.
Good luck.
