Do you know how much your car and trailer weigh? I'm not sure on the 2 door, but the 4 door is rated for 6,500lbs with a 500lb tongue weight. The tongue weight goes up to 1k with a weight distributing hitch. I tow a camper weighing around 4,500 and it does OK. I wouldn't personally go any more than 5k with mine.
Look around here for common problems. Check the transfer case for signs of wear in one particular spot on the case. Check the ball joints - those alone are $700 or so unless you can do the work yourself. Stuff like that can add up quickly if it hasn't been done.
