If it's anything like mine, the wiring is appalling. Had to rewire the water heater as I couldn't trace the supply to it. If an electrical engineer couldn't do it, what chance for the rest of you? When I get the time, I intend to remove all the wiring and rewire all of it, wiring the fridge to the 12S socket rather than the battery too.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
