Julie,
Thank you for taking the time to post the information from the IRS as well as add your comments. That was very informative. Being that my wife and I are both full-time educators it doesn't appear as if it would be worth the time, effort, and possible risks to pursue this. Of course we would keep good records and keep everything on the up and up as we do our personal finances and taxes but the potential of us ever having a year where we actually make money would be very slim (especially if you've seen the way I drive ...

). We only do this for the fun, travel, and to meet new friends and don't want to risk an unneccesary audit or aggrevation if there isn't anything to be gained from it.
Also, thanks to those of you that have posted about having a CDL. I coach varsity softball and coaches in Texas (non-union state for teachers) drive their own buses and have to have a CDL. One nice thing about that is we get a discount on our RV insurance for having one.
Thanks again Julie for the help as well as everyone else for some great and informative comments!
Scott
