Inexpensive monthly RV parks?

I'm not tied to any one County in North Carolina, so I'm flexible for the entire state. I'm looking for a relatively inexpensive RV park or campground with RV hookups that has monthly rates. I'm physically disabled so I don't necessarily have to be in a city. It would be nice but it's not a requirement. My preference would be no more than 30 minutes to cities that have the basic necessities of life.

My ideal location - Not requirements.

15 minutes to a city

Not overly bad condition with not so good people to live around (drags, criminal, constantly loud, trash etc)

A city that has cabs and or urbers

A city that has 1/2 decent social services

Has Wi-Fi (I want to go back to college virtually)
