What is the condition of the unibody on it? Get some pictures of that?
To me, it looks like just the sheetmetal stuff is rusting. I bet the frame on it is in okay shape. Usually the right rear rail will get a hole behind the bump stop.
Also, while they are unibody, they suffer from frame rot a lot less than Wranglers. The aftermarket now produces many, many options for weld-in frames. My 2000 will be getting one soon.
