From the following page: https://northcarolinastateparks.reserveamerica.com/camping/william-b-umstead-state-park/r/campgroundDetails.do?contractCode=NC&parkId=552839 "Our sites are meant for tent/pop-up camping only. No RV or Trailer is accessible."
Camp Lapihio is a group campground inside of Umstead State Park. I have not seen any RV connections at the campgrounds. I would check out the umstead state park website to verify if the have an rv parking area.
