I just put a Reese hitch on mine. Product # 33018. Turned out pretty good to me. Fits behind the bumper and fills in the bumper trim thingy if you have it. Very solid, although I haven't gotten a chance to test it yet.
Found it on craigslist for $50. $10-15 in hardware and it was bolted up, no drilling needed. You will want grade 8 bolts or better. Otherwise I don't think any other models have the same holes for the frame as ours. You could always drill new ones but it's not really a great idea.
Current repairs needed:
back Shocks,Clunk from unknown (found), diff fluids
Soon to be: muffler
