For me, there is no "Other Than Craigslist" for free advertising stuff for sale including something like a Tracker.
Unfortunately, there are a select few who appreciate it setup for being towed. But the general public will shy away becasue they don't know how many rolling miles it has. You might be better off removing all the towing stuff and sell it as just another vehicle. With rare exception, nothing sells a typical vehicle better than "stock/unmodified".
Sell the towing hardware separately. Take pictures now while it is still on your Tracker, then use the pics for your hardware sale. Be sure to save every nut, bolt, washer, etc. and include them in your sale pics. Also include any paperwork, installation instructions etc.
