Warn Multimount Hitch???

Has anyone used one of these in the rear receiver, of their H3?
Seems like it would be a real easy solution to wanting a hitch and not having to completeley disassemble and replace the front bumper.

I suppose a Snatch block or Two might be neccessary, and where does the the power come from? Leads that manually attach and run back to the battery?

Any thoughts or user experience would be appreciated.
