Yes, I think the segments are actually filmed in a little apartment.
Looking at the index of her 'channel' he has lots of those vids, so I guess she is making a little $$ on it from ads or whatever. Found her youtube niche.
I watched 2 more of them, and in one, she moves over to the sink to rinse some ramen noodles she was going to fry..it showed the kitchen window and the paint is really peeling off the sill, as if it really was an older mobile home.
The other was 'jailhouse burritos'.....pretty nasty looking.
(I'm guessing she knows 'how' to cook, or at least how to eat...she didn't get that robust shape by not knowing one or both..in one video, she said her nickname was "Haystacks')
