We are about to embark on a 3 month trip into France Spain. Our van an Autotrail Cheyenne 660 SE 2006 reg has two 6kgs Propane cylinders. The master plan is to leave one of the cylinders at home. Then buy a Camping-Gas cylinder with an adapter and hose to connect to our existing 30 mbr Truma regulator. When this cylinder is empty we then switch to the Uk Propane cylinder as a back up supply. We then of course purchas a further Camping-Gas cylinder. This seems the cheapest and most practical way round the problem. Does anyone have any ideas? I have been told one can buy an empty Camping-Gas cylinder at our local re cycling centre. This we can exchange for a new one when we are abroad. Many thanks in advance for any advice.
