Yep, I think things will break with some frequency. We have two little dogs that she always hates to leave which will make this a plus. I don't think there will be any great savings but the getting there will be an adventure.
The two real big expensive things appear to be the refrigerator and the Onan generators. The reason I went old and cheaper is because at 70k for a new one you lose 15k the day you drive it away.
If we learn to hate it, we are not out that much with older. I do agree it will be a mini money pit.
I already need to spend on a string of Jalapeno lights for the awning and a LED palm tree.
