keep in mind they aren't making rbv's anymore. do you really want to trim fenders, thus lowering resale/collector value? body/suspension lifts can be reversed. most drive train mods can be reversed. start cutting and there is no reversal, only replacement IF you can find the right body parts.
just a thought.
for the op, if you're lifting for bigger tires, don't forget to figure in re-gearing to get back the power you'll need to move them efficiently. and don't forget that locker that will help immensely in the traction dept. these things aren't cheap, but for any tire size over 30/9.50x15 (or 235/75x15) you'll be needing them for sure... imho.
