Not sure. We met a couple in a 31ul at James Island park in Charleston a couple of weeks ago. Also, I mention the Skidaway Island state park in Savannah. Almost every site is pull thru and a few have sewers. Beautiful park and city. We're outside Asheville in our third week on the road. Riding motorcycles on the Blue Ridge. Hit a short, hard core, rain yesterday, and my wipers did not fall off!!! Enjoying our camper.
