If your interested in renting your RV, check out RVShare.com. You don't hand it over to some company. You can even opt to take it to the CG and set it up, and take it down and home afterwards. The people next to us at Stone Mountain this year rented. They left and the owner came and cleaned it while still hooked up. And all the warnings stated here are covered.
Not everyone who rents is sub-human like people here seem to think. At the end of the day, its your RV and you get to decide how to use it. Just tell your renters to shut the porch light off at night... :W
