Gas Connections - German to French fittings

[Suze]

Has anyone had experience of changing over from German gas bottles to French LeCube bottles? If so we would be very grateful for advice on the fittings/connectors/adaptors needed. The Gas Cabinet on our Hymer which was bought in Germany is not big enough to accommodate 2 X French 13KG bottles, which we did have the correct adaptor for, so we think the LeCube is our best option, but this seems to require the fitting of new hoses etc. We currently have a bottle top fitted regulator, rather than one fixed to the bulkhead. Many thanks.
