My 2006 4.0L auto LJ (same as the TJ just longer wheelbase), Owners Manual says its GVWR is 4600 and its max trailer weight is 3500. The same owners manual has all other 4.0L TJ Wranglers listed as GVWR 4250 and MTW 2000. with the actual curb weight of the Wrangler being around 3500 lb.
Since most Wranglers don't come with factory hitches, its usually an after market hitch. Mine has a class II 3500 LB frame mounted hitch and all I ever pull with it is an ATV trailer with 1 or 2 ATV's; probably just over 1800 lbs total including the trailer. I only tow from my house to the trailhead, for longer trips I have a toy hauler RV.
