Subject comes up pretty often.
RV rental managers put a pretty good spin to their advertisements to entice folks into handing over their RV in return for some money.
The Rental managers have zero invested and act as the middle man for the transaction, they assume zero liability, zero risk, zero loss if things goes sideways.
I once had a Supervisor that bought old run down city buildings to rehab into apartment rentals.. At one point he owned 2 city blocks worth of buildings.
Sure, he made money for a few yrs but he was constantly battling damage and repairs from the renters.. Oh, the stories he told about the aftermath of the messes which are not repeatable on this forum..
Keep in mind, if he bought property and then built new buildings, he would have gone bankrupt! He was able to make money because he bought much of the properties on Sheriffs sales which were defaulted on taxes or loans.
Last time I talked to him 5 yrs later, he was in process of unloading all of his rental buildings, said the money was good but the hassle and intrusion in his life was not worth it.
I know it grinds on folks to have spent so much on a RV that sits for 95% of the yr doing nothing, but RVs degrade fast enough with care from the actual owner. I can't imagine how much faster a RV will degrade after a couple of rental trips with folks that have zero invested interest in your RV..
If you want to try renting a RV out as a business model, you will be money ahead to buy a older well used RV for cheap and fix only what needs to be fixed as needed.. When it becomes cost prohibited to keep up with repairs, sell it off cheap and find another cheap used one.
