Follow Up: 4 Runner Towing Reality

Agreed. You simply can not reasonably tow what you want with that. Sway control helps, but it will still sway unless you get a Hensley or p3. You would need towing mirrors too. I've been there. No way you could tow it for 5 hours straight either.... Just too nerve racking.

Have you considered an class c or older dedicated towing truck? Maybe something from the early 2000's? Or even a used E350 work van? This could be a low cost solution.
