>>... To put some rough numbers on it -- there are about eight million RVs on the road in the US and roughly 3100 fires per year, of which three quarters are caused by 12v electrical systems. -  So roughly one in every 2600 RVs has a fire each year, and roughly one in every 10,000 has a fire that is not caused by 12 volt electrical systems....<<

  Thanks for giving us some perspective, David.

  Our 12 volt heater is pretty ineffectual in hot weather so I'll
continue to run the fridge on propane 100% of the time that the bus
doesn't happen to be parked  within a hundred feet or so of an
electrical outlet.
