The Flagstaff Micro Lite XLTs all appear to be 18' trailers with a GVW of 3,500 to 3,800 pounds. I would think that you could entertain towing that trailer successfully if you aren't going to far (or too fast). Keep in mind that a Wrangler type of vehicle might be a bit less stable platform than average because of height, width, length characteristics. It certainly wouldn't be among my choices for towing but, since you already have it, the Micro Lite XLT might be doable. Make sure to check your manufacturer recommendations and limitations on your vehicle.
