our jimmy's falling apart, so i'm gonna have to buy a new tow rig. i'd only be towing a 17ft boat, so a v6 cherokee should have enough power. the problem is i can only afford a beat up high milage cherokee because i'll only have about 2-3 grand the spend, if that. how reliable would a higher mileage jeep be? i just need it to tow a boat about 20 miles, do some winter driving, and a little offroading, can i rely on an early 90's cherokee to do this?
