Just do it. The Caravan club sells a guide to campites in Europe written by its members. Also the CC offers lots of support just get all their tec. sheets. If you can't do it get a caravan workshop to make you up a reverse polarity conector lead. Remember that it will be the Easter hols. so some sites may be full. We go to Europe every easter. Just take lots of time to plan as you will be away from your usual support network. Then just go there and drive round. The Loire area is beautifull loads of Chateau.
