We spent many years at the beaches in SC. First at Ocean Lakes for 15 years or so & most recently at Huntington Beach State Park at Murrells Inlet. Haven’t been for a few years now, but highly recommend Huntington. They have several fill hookup sites, the newest with concrete pads. The new ones are tight, but have access to A/C bathhouse & concrete walkway to the beach. Last year we checked out Gulf State Park in Gulf Shores, AL & going back there this summer. Campers drank openly at the state park.
