Medium-sized V8 SUVs can be good tow vehicles, as long as you're being reasonable on trailer length, and using a high quality Equalizer-typr, dual-cam type, or Hensley type hitch. The wise members of this group will alway caution you on your Jeep's 110 inch wheelbase. I have a comparable vehicle in wheelbase size (114 in) and tow rating (7,000 lbs), and it tows the 22 ft well (trailer 3680 lbs loaded). With the larger V8, you'd have plenty of power/torque, but for handling and control a good antisway hitch is mandatory. I certainly wouldn't go any bigger than than a 22.
