UK tunnels can be used by vehicles carrying removable cylinders provided the gas is turned off at the cylinder valve, though there may be a limit on the total amount of gas carried, normally well in excess of the amount on a caravan or motorhome. Rules vary on the continent and you are advised to contact the Club's Travel Services for specific advice before travel.
Roll-on roll-off ferries have similar rules, though there are some variations both in the UK and continental Europe so check with your ferry operator. Generally, the number of cylinders you are carrying must be declared to the ferry company and to ship's officers, and there must be no more than three (two in the case of some operators). All must be secured against movement and shut off at the cylinder valve during the voyage. Eurotunnel currently permits a maximum of 50kg of gas to be carried with the portable cylinders and 47Kg for a fixed installation both turned off and isolated.
If you have a motorhome with a fixed LPG tank be aware that some tunnels and ferries may limit the amount of gas that can be carried, so check with the operator first.
Gas supply hoses deteriorate over time and in use, so they should be replaced at least every five years and more frequently in intensive use conditions. UK hoses will be marked with their date of manufacture and should be inspected frequently for damage and wear.
Make sure all hose clamps are sound and the hoses are positioned so they will not become damaged by other items or loose equipment.
Some caravans have an external gas port for using a barbecue. While this is convenient, it is important to observe some extra precautions when using such a device. Using an external gas cylinder to supply gas to the caravan through this port is not recommended or permitted on Club Sites or at Club events for safety reasons.
All cooking that uses a naked flame must be done in an area with adequate protection from flammable material. In the Club's opinion no barbecue, using the caravan supply or with its own cylinder, should be used in an awning because of problems of ventilation, carbon monoxide build up, smoke inhalation and fire safety.
Make sure the supply hose is located away from area where people walk and only an approved length of hose is used. Remember that a gas barbecue can use a lot of gas and it may be advisable not to use other gas appliances at the same time. Your caravan handbook should give advice on this point.
