Yeah, I think the CV's definitely need addressing, but remanufactured ones can be purchased for about $150 or so with a lifetime warranty at Kragen or Autozone.You might be a little high on the price. I sold a '96 with 150k and 3.4 for $5700. Looks like the cv's are needing replaced. Good luck with the sale.
...sorry, just noticed that you addressed the cv issue...there is no way you will get 6k for that truck...IMO.
