The park is mostly 55+ residents. There is is only one 5th wheel near us that is under 45' and they have teen in the home with them. When you say long-term, do you mean more than a year at a time. Our experience is that you first stay 6 months and then they offer an annual term. One part of the park has what I would call permanent homes. These are setup on blocks, tied down, and skirted. The premier RV spots are nice. You have lots of space on each side, a very quite area(sure in part on there bring no small kids), and decent amenities for a park like this. Not sure if recommend for young families though, mostly because the isn't a good play area and they are so many old people.
I would call the office and ask.
