Yeah. Also, the "do you want to live in a trailer park anywhere?" comment reminded me that yes, there are some you might want to live in. There are good ones and bad ones. There were three trailer parks around where I lived, and I eventually lived in two of them after high school and during college. A friend eventually moved to the third.
One was a very well maintained park, with named, paved roads, well landcaped property, well lit, etc. As far as mobile home parks go, it was quite nice. I enjoyed living there. (Google image search "nice mobile home parks".)
Another was more middling, but not trashy. Older homes, some in need of repair. Some of the cliche images when people think of trailer parks - old cars out front, poorly built, aging wood decks, not as well maintained property. Generally lower income folks trying to get by, with the occasional sketchy neighbor.
Then there's the one outside of town, that was basically a loosely organized dump with aging mobile homes dotted around it. I feel like the comment was referring to that last one, which is how they tend to get portrayed. That's our collective mental image of trailer parks. But that's very much not how many of them are.
Sorry for the derail, just filling in some context. "mobile home park" tends to conjure one image where there's a pretty wide spectrum. I don't like seeing it used as shorthand for anything. Clearly, she was poor, though.
At any rate, sorry to hear Moran passed so young. I was not aware of her situation after Happy Days - I recognize her from the photos - but life was not kind after the show, it seams. RIP
