Well, make sure everything works (cruise, A/C, windows, wipers, defroster, etc.) 

- Check to make sure the truck will go into low range and that the center diff will lock (yellow indicator turns on on the dash) and unlock. DO NOT lock the diff while on pavement, get into at least
a grassy area while on a test drive and try it there. The linkage for the center diff and lock will oftentimes not have been used by the prior owner and jams up -- it's about a $500 repair to replace and install a new linkage, so it's worth checking now. IMHO don't buy a truck where that lever won't move.
- Check the diffs and transfer case for signs of leaks (esp. at back of x-case by parking brake assembly).
- Check for signs of oil leaks (although they all leak, it gets obvious if it leaks too much -- there'll be oil splahed all over the inside of the engine compartment).
- Check for rust on or around the outsides of the alpine windows.
- Check for rust inside the door jamb areas.
