On the insurance issue; when I used my condo in Branson for my personal use only, I had a regular insurance policy. When I put it in a nightly rental program I had to upgrade to a commercial insurance policy, about 20% higher than the personal policy. Check with your agent, he'll know. I really think that will be your biggest issue, you just want to be covered in the event a renter has a serious accident. You might check with the people who rent RV's for a living and get a copy of their contract.
You will probably want to get set up to accept credit cards for payment, plus you can use the card as a backup for damage. Lots to think about but it can be done.
