Well I know my dad's truck (the one in my sig lol) KBB's at $10,400 on the higher end. But the body isn't in the BEST condition (some rust, dents, scratches, and a little body damage on the bed). And it's higher miles. I have no real idea but I'd expect that truck to go for maybe 12k or 11k, something like that. Sounds like a nice rig though. You have to get the vibe from the guy that he (or she) knows the truck well and has taken care of it. If they don't know how often they change stuff like the oil, air filter, etc then i wouldn't trust 'em.
Don't feel like an a**, I had that list pointed out to me too lol
