Sure this will sound daft to experienced motorhomers,but I'll ask anyway! With regard to electric hook up. Am going abroad soon and just realised I havent made any provision for the fact my 3 pin plug wont fit abroad!! Am assuming the normal travel adapter isnt what I need, so what do I need? Also am slightly puzzled by this reverse polarity thing, what is it, how do I check it? Do I need a tester, if so where do I get all these things from? Thanks.
