Found the RPO codes. Got a GU6 or 3.42 in addition to a Z82 tow package. From what I can tell from reading other posts, a 3.42 is not exactly the ideal rear end to tow with. I think I'll take Traveler's advice and keep it out of overdrive.
I also found a site on an old post that lists RPO codes and their definitions. As of this posting, the site is still active, http://www.princeton.edu/~patrickm/rpo.html
Thanks again to all.
