I have recently purchased a small caravan to go touring around France from our home in the Charente Martime the caravan is from the UK it came supplied with one 6kg propane cylinder.When this gas runs out with what do I replace it or refil it.The regular is different to one we have in the house and the bottle connection is also different not to mention the fact that the caravan bottle is also a great deal smaller than the house bottle. I have visited the local supermarkets and to date been unable to see or find out what I need . I have a feeling that I may have to purchace a second bottle in the UK and bring that over and keep replacing them that way, unless somebody has also experienced this and can help.
