Well, You aren't going to have much luck with your truck. I have been in the buying/selling/trading game for awhile, my family is into it. Bottom line is with most vehicles, its not a lack of desire, its a lack of funds. There are plenty of people who would love that truck, but not very many people who have over 13k just sitting around, waiting to be spent on a truck.
Plus, the 1996-2006 vehicles as a whole, if they are american brand, are terrible. Nobody that knows anything about vehicles wants something built between 96 and 2006. The worst decade ever for american car companies.
And let me ask you this, what type of diesel is it?
