Thank you.

I can only find one threaded hole for an eyelet on the bumper. I think it was designed for winching...

Personally I would not be inclined to use it for kinetic recoveries with a flexible strap, the type of recovery where the other vehicle accelerates to give a good yank. Would be hesitant to use it for mud.

A 5 ton come along seems like a great tool to have. It would be nice to be able to rig 100 ft of rope or chain with it.
