Hi Karen,
There isn’t much difference as to a normal booking, except that it moves..
Setting up a Legal Agreement covering all your needs and having the guests sign it is the most important part I guess.
When you google/bing/yandex “Rent RV” the first OTA’s which pop up, are the ones you want to list on.
Great idea just popped up.. since you said “our RV rentals” - why not providing a solution for others who have an RV which is catching dust as well? You might want to use the “Hosted Websites” to provide a website per owner and/or create a centralized one with all RV’s on it.
If you have specific questions, please ask them here so that others could learn.
Good luck with your new business!
