I was reading another post, and went to the Dave Newell web site. One of the items he has recently got is "Polarity changeover switch". In the description: Dave Newell - Motorhome, Habitation, Servicing, Cruise Control, Camos Domes, Satelite Tv, Reversing Cameras look under 'Bits & Bobs' They suggest and I quote "Foreign campsites are notorious for having reversed polarity on their hookup points which is potentially very dangerous." Is this true, A: Foriegn camp sites are notorious? and B: Is this a dangerous issue? Any advice and help is much appreciated as we will be getting our first MH in the next few weeks and will be going to Europe a great deal. Thanks. Adge.
