If anyone out there is looking for some good Information on Vehicle Recovery you shoud check out the DVD Getting Unstuck By Bill Burke.
Here is the link

Bill has some good Information on winching and some good stuff on the Hi-Lift Jack and how to use it as a winch for Recovery.
I found the video to be helpful and I learn a few things that I can use the next time I have to winch.
