A few days ago there was a guy sitting in a rented motorhome with the engine running for about half-an-hour while still plugged into the mains. It was kind of early in the morning and when I got back from walking the dog he had left so my curiosity about this was never answered. :Blush: All I can think is that he was using the demister to clear the windscreen of condensation before driving off.
I thought running the engine while on hook-up was a no-no. It's something I've never done but realise that I don't actually know why. Is there a risk of frying the batteries if you do this?
