Wilson,

For safety, if you are able to, pick up a recovery strap from autozone, and shackles, so if you do get stuck you have the tools to get out,
visit this site: it'll give you a good idea on what to bring.

Pick up some extra coolant and oil, just in case.
See you on sunday if you are able to.
