One thing not mentioned in the video was the extremely high load the anchor points had during his winching.
People talk about using a 4:1 or 5:1 rigging to increase the pulling power of the winch, but most don't mention strength of anchor points. I'm not talking about the moving (winched) vehicle - I am referring to the fixed ones. The moving vehicle will not see nearly the load of the fixed ones, as the load is transferred to motion.
Which is a MAJOR consideration and why it's good to stop and think before any hard pull. Mire factor (stuck up to the frame rails in deep clay mud etc) and rolling resistance should always be considered as well, and is often overlooked by the "hook a chain to it and floor it Bubba!" crowd.
Properly rated recovery points may not be up to the task of a 4 to 1 in many situations, which is why we encourage the use of a bridle (double) attachment to a vehicle rather than yarding on a singe point.
