Jules47. There have been untold thousands of gas bottle fires over the years, but that's not the sme thing as a pilot light on a fridge burning down a service station.
neilnruth, Can you or anyone else supply some more information such as a report from the Fire Authories, Office of Gas Safety, or even a newspaper article that points the finger at such a fire and its cause happening in this country. Until such time as I see something definitive it will remain an urban myth in the realms of Australian Vanning. But I agree, it ain't a good or safe practice to tow with the gas turned on for any reason. The same can probably be said for those that run a 12v DC - 240V AC inverter to power the van while on the move.
This comes pretty close John http://www.caravanningnews.com/banka.htm back in 2009, blamed on fridge pipot light.
