Just would like some advice.....pros/cons ....of buying a used C-class RV from one of the large RV Rental companies. They have some great deals, the RV's are only a few years old, but they have over 100,000 miles. I dont think it is a good deal, but would like to ask those of you out there who either have bought one to let me know what you think? Are they good deals or a disaster waiting to happen?
