Just a tip for anyone who plans to attempt this. Do not use a tow ball to pull anything like this the way he showed in the video. Those trailer balls aren't designed to work like that and they can suddenly snap off, and become a projectile. There is an actual towing clevis you can install into your receiver that allows you to attach a strap that is way safer.

+1 for ditch the running boards. The trailer hitch as well unless you plan to use it or need a strapping point. If so then one of these https://www.amazon.com/Smittybilt-29312B-Receiver-Shackle-Receivers/dp/B001CF1A7O and an actual recovery strap which is different than a tow strap. The best thing you can ever get for 4x4ing is a FRIEND to go with vs alone.
