We currently run just the two gas bottles which I suppose is the norm but what does one do when your Calor gas or whatever are about to run out.... I believe the best cost effective solution is to carry a full bottle from home and a refillable bottle like the AutoGas ? alloy refillable bottles which I'm given to understand uses different adapter hose connection's for different countries...sorry cant afford the expensive GasCom fitted system...you know the yellow bottlesoh:
