Thats a tough one. Thinking from my perspective, I would be going after the powertrain components. Engine, Transmission, Transfer case (assuming its a 4wd) and maybe even front and rear diffs, CV Half shafts.
Also some electrical stuff if in good shape. ABS harnesses, O2 sensors, catalytic converters.
Interior stuff would be awesome. The rear cargo area in my 05 has taken a beating, and its the plastic type, not carpet. I haven't found any replacements for these, so probably the rear sets, as well as the panel over the spare tire wrench.
Stereo, amp, speakers, subwoofer (assuming its a BOSE system).
Check for a di-chromatic rear view mirror with compass, I have one and its great.
