Retired Couple looking for RV Site

My parents are both semi retired (60yo). This is their second year coming to the island seasonally. They are looking for a place they can park their 40ft long RV and settle in for the season. They are staying from October till April. Hopefully leave the RV there till next year and so on. They are in a bind this year as they thought they had a good place to park for the year but that fell through so are needing a place asap. They are kind, hardworking, respectful and friendly people. They would make great neighbors. My Mother is a teacher and exceeds at gardening. My Father is a Plumber and can do any handy trade needed. They are looking for any sort of site asap. Hook ups preferred but not required. Price depending on amenities. Thanks!
