The tiny house in a resort splits the difference between home ownership (ugh) and apartment living (which I loved). Someone else takes care of pretty much everything except your actual house, and they have a ton of people around who do that as a business.
The problem with the motorhome is that it's like a car: after so many years they stop making parts for it. It should be a simple thing to take the RV in with a punchlist and they fix everything, but if it needs major parts it becomes an issue.
But this motorhome isn't that bad - like you said, everything is going to require maintenance at some point. Levelers are a problem but we can always level manually with our cute yellow blocks.
It's a little rocky with just the wheels on the ground but nothing we can't live with.
