$10K sounds really high. I paid $7500 for mine a year ago with 170K mi. Had 50K on the short block, 25K on the DTT trans & Dynomite injectors. New batteries, excellent mechanical & interior. In other words, what I paid didn't even come close to covering what the PO had spent in the last 2 years or so.
Paint peeling on upper door frames and a little on the bed rails & fender tops, but still looked pretty respectable. Hood & roof had been replaced due to hail damage, so paint was good there. Bought it in Austin TX. Around here, I'd say the truck you're looking at would be $6-7K max.
