Almost impossible to say from those photos and without knowing what you are looking to do with it once it's yours....
With the 1st Gens it's all about the rot. For $8500 there had better not be any, but I'm sure that paintjob it hiding a number of sins. It doesn't look like it was done by someone who really cared about the prep and underlying metal... just wanted a "fresh" looking truck. To me, a paintjob like that is worth exactly $0.... I'm going to need to strip it all off anyway to see what I'm really dealing with.
Bumpers are horrible, so those go in the scrap pile. Factory A/C is nice, but only if it works and blows cold (which I'll bet it doesn't). My guess is that the axles and driveline (with the exception of the engine) have never been gone through, and the suspension is probably stock or close to stock with dryrotted bushings, etc.
If you are going to swap in new suspension and axles, then that stuff doesn't matter but don't pay a premium price for a truck where 80% of it is going in the scrap pile....
