I am spending next winter in my van abroad and plan to be away for 6 months. The van is only a year old and has the gas regulator fixed to the van inside the cupboard where the gas is kept. I presume when I run out of the 2 calor cylinders I have I will have to buy a Camping Gas cylinder. If so can I buy a connection from the Camping gas cylinder to connect to my existing pipe that goes to the regulator. Also any other ideas about connecting other gas bottles purchased abroad.
