Ah well, if it is unoccupied, and gets driven off to be used then the situation is not as severe as a formal caravan park for visitors - I'd  be less worried about tent pegs and so on, even assuming the SWA runs under grass and not either a paved area or alternativley is clearly visible. Actually, just for occasional charging and so on, I'd not be that phased by the PME either, it is similar to a lot of car chargers. (ignoring legislation, there must be plenty of private vans that are essentially on an extension lead from the house with no thought at all to earthing)


However to do it properly, an MCB and an RCD or a dual pole RCBO, and suitable socket, and as noted the islanding of the earthing. Have a think about the routes of drains and gas pipes etc before hammering a rod in willy nilly, or the cost goes up rather a lot.
