I've heard of people renting a spot in an RV to park with their tiny home/rv/airstream as a STR but have been calling around lately and have been getting shut down.
Many parks say they don’t allow tiny homes and every one has said they don’t allow short term rentals.
@Graham F. It would depend on the area and the property owner of the land itself. Your best bet would be to look into areas where they're already doing this to see what next steps you can take. Best of luck!
We have tried to do that as well. Most of the RV parks around here have spots for annual rentals, but they don't let you airbnb the camper with that program.
However, we rent our camper out. People book the campground and we bring it to them for their stay. It's worked pretty good for us and for people that want to try out the Camper/RV lifestyle without buying a rig. It's just more work because we deliver and pick it up.
If you wanted to do a tiny house, you would most likely have to buy the land first. I'm hoping to do that this year.
You could try doing it in your backyard. Why must you park an RV in an RV park? Just connect your RV to 30 amp service, run a garden hose, and run your wastewater line to your cleanout hole. It's not rocket science.
