On PEI, see if Twin Shores (
www.twinshores.com) has space. We have been camping here for more than 30 years and have a large 5th wheel now but have camped in a 40' motor home, too. It has a beautiful beach, great staff and facilities. If you camp there, look us up on site S13 and S13a, New Hampshire plates. We are down by the beach. Have a wonderful trip!
