I Googled Manhattan hostel and found some very interesting links including one for the
Harlem YMCA The OP can research the rates himself, but these are typically way less expensive than an apartment and according to info at the link I provided, you get to use the Y's facilities including pool and computer room.
No way in HE double toothpicks would I even consider living in an RV in the north during the winter.
It's funnny how these types of questions pop up at this time of year - last year, it was about a guy wanting to convert a box truck into some kind of living quarters so he could park at the university parking lot - un-noticed.
I can't see any outcome other than being found imitating a popsicle. Good luck OP - if your still around reading these replies.
