Dude, a cherokee with 32" MTs and a 4" lift is a GREAT vehicle to start wheeling in!! All you need are lockers, some armor and recovery stuff and you'll be able to do some pretty nasty trails for dirt cheap. XJs (that's the designation for Cherokees) are very popular wheeling vehicles because they're cheap, readily available, parts are so universal that they're cheap and very readily available, it already has great suspension stock and they're really cheap/easy to modify and make ridiculous. They may be more common on the trails than short wheelbase jeeps (wrangler type including CJ/YJ/TJ/JK). Grand cherokees are also good, but a little more pricey, and the trannys in them suck. Does that cherokee you have have an auto? If so, you're in luck! Change the fluid and filter, throw a tranny cooler on it and it will last forever!! People swap them into TJs for rock crawling...that's how good they are! And yeah, the 4.0L inline six is one of the best motors for wheeling, hands down. Ultra reliable and a nice smooth torque curve.
