I have had a few rental properties over the years, I know its a different animal, a rental RV vs Rental home, where it is long term. However you have to deal with "people" and that is the biggest pain there is.
Forget the pitfalls of some one unfamiliar with your rig, and probably all campers. All the problems associated with the use, and of the loading and unloading and various operation. Just dealing with people and their complaints, problems and securing the payments, can be a nightmare.
Of course not all people will be a problem but people can and will be odd and will for sure not treat your camper with the same care as you, who have earned and cared for you camper.
My advise is do not do it.
If you must rent it out, get your frame of mind to the idea of this is a business, and try to not have any emotional attachment to the camper
just my opinion
