This truck looks to be in good sound condition, BUT, lots of work will need to be done to make it roadworthy. Motor work, interior work, wiring probably is chewed up by mice, stripping the paint and a new paint job, and much more. A fair price among friends in this situation, would be 5-7 thousand dollars, probably at the lower end, around 5 thousand. Depends how bad you want it. 28-29's don't have the value of the 30-31's. Hope you get it.........
hardly an expert, but this is about what I was thinking
