The XJ Cherokees could be equipped to have a tow rating of 5000 lbs. That was with weaker axles, smaller brakes, unibody, shorter wheelbase, etc. The JK with a real frame, stronger axles, bigger brakes, longer wheelbase, etc. A theory of mine is that the corporate lawyers have cold feet possibly due to the JK not having a fixed roof.
1st one- 1989 Cherokee Laredo. 12 great years
2nd one- 2001 Cherokee Limited. Got it before they were gone.
