I've never had to atop at an RV park but I've read where others have. If you can't make the next SC, an RV park is a lot better than being stranded. I ALWAYS carry an EVSE (cord) with a 14-50, 6-50 and 120V. I also carry a spare. We've got near 80,000 miles on two Teslas with more than 15,000 on...
