I need some advice: I want to tow my boat with my XJ ('96, 4.0L, 4.5" RE lift, 32's, 4.10 gears, auto-trans). I'm going on a fishing trip in the Sierra's and want to wheel and fish. My boat and trailer weigh 3800 lbs. Probably will add another 1000 lbs of people and gear. Does anyone tow fairly heavy stuff in the mountains with their jeep? I'm within the GVWR rating and towing capacity, as per the jeep manual, but I'm worried about overheating or frying the tranny.
