I've put a lot of thought in to doing the same, but can't get over the idea of trusting the general public to not destroy it.
Have you had good luck with it not getting beat to hell? To most people know how to use it properly?
Ive had more issues with the RV falling apart on its own then people destroying it. Ive had a handful of people cause minor damage to it, 90% of those events happened when people towed it themselves. Including...
One guy...
Scratching the sides on brush or trees - buffed out
Cooking with the glass stovetop cover down - replaced glass
Another guy...
Dragging the wiring harness - replaced
Leveling the trailer with stabilizing jacks - replaced bent arm
Kitchen table corner cracked from it falling while in bed mode - not the fault of the user, designed like $&?!.
Rv issues...
Oven dial imploded- replaced.
Fridge thermal fuse blew - replaced and built a custom baffle to prevent it. Fridge single cooling fan went bad - replaced with 2 computer fans.
Water heater went out due to faulty circuit board - all replaced.
I fixed almost all of those issues myself and none of its technically under warranty due to it being rented.
I live where I can and have time to deliver it to nearby campsites. I charge $10/mile to deliver and setup/take down, max 65 miles from home. Aim for $100/hour for my time and use of equipment.
So best thing I can say is try to deliver it instead of letting people tow it. You maintain control and make 2x the money. I still block out any dates for my well planned vacations, but sometimes we use it randomly when it has no renters. Will pay for itself in 3-4 years and decreased tax liabilities by an equal amount at the same time. Usually doesnt get rented much during hunting season too so theres another bonus. If you already own yours outright, its just easy money.
