Character note.

Sarah would genuinely prefer to live in a worn out Microbus hidden away in an abandoned junkyard a nice house in the suburbs.

She may, in fact, have done so for a while.

It's partly because of her trust issues and having been burned by the system, partially because she does, in fact, come from a small town/village and woulnd't be comfortable in a nice house in the suburbs, and partially becuase she's been roughing it for years and is kind of used to spartan living.
