I don't really mean to go off but, come on.
Why not just say "Truck For Sale" or even just "For Sale"?
You want to sell it but, you can't describe it any better than that?
What motor? What trans? Not even what color?
You honestly want to answer 100 phone calls to answer the questions you could have answered in two lines of type?
A good description would leave you to answer calls from actual interested parties.
