If you are talking about a 2dr, drive train strength is not the limiting factor, the safety of the short wheelbase is a concern. The short wheelbase is not as stable in the wind or stopping, so jackknifing is a real concern. As live_slow indicated, drive very conservatively and consider brakes and stabilizers. I pulled a 2,000 lb landscaping trailer from Ohio to NC through the WV mountains with no issue. Actually, the Jeep/trailer combo rode better loaded.
