can you park an rv overnight there.

Yes you bet

Probably, yes

You should be able to park at the hotel next top the outlets...

You need to call them and ask

Yes

I'm sure you could as long as it ain't some old piece of junk beat up thing

I work security at the mall here at the state line. You can park during the day, but there is no over night packing at the mall. At the casinos yes.
