I paid 8500 for an 02 with less miles(110k) about 2 months ago. Needed about $1000 worth of work(clutch, axle seals, pinion seals), but had brand new(almost) BFG AT's.
My frame has some surface rust, but is still solid. I have my carpet out currently for spraying the tub with bedliner. I have some rust and minor corrosion I need to take a wire wheel to, but overall its not bad. No holes. So that may just be what you are seeing.
Depending on the real condition of the frame I would say 7000-7500 or so. Thats basically a complete base model too.
If I was in St. Louis right now I would go look at it with you, but I am out of town until Sunday. If you want to check it out next week I would be available.
