[Milsurplus] Little "Field Day" Genny, Remarkable Price.

One must remember that one is buying "LPG" when purchasing "propane" gas in the US. By definition LPG "may contain" up to 5% butane gas for the US market. Foreign markets, primarily warmer climates mix LPG at butane contents as high as 75%. Propane has a boiling point of -42 F. Butane's boiling point is much higher at +31 F.  Thus at max "permitted" mixture LP has a boiling point of -38 F which in these Northern areas approaches ambient low temperature during a severe cold snap. Having used LPG as a portable heat source in extreme cold I never exchanged a cylinder that ran low at extreme cold as it would yield usable pressure as the weather improved. It is conceivable that the refrigerant properties of a high volume draw on a cylinder will also effect gas pressure realized. Also LPG sold for use during warm months may exceed 5% butane and not be noted as such during summer use.

Yes, Propane is good but requires consideration in cold weather.  I have 
a dual-fuel generator, gasoline and Propane, which is a great comfort, 
but at 50F or below I have to set the tank to be warmed by heat from the 
engine or it won't go.  Once I was exercising it on Propane at 50F and 
it quit with a quarter inch of ice on the tank. I think permanent 
installations have tank heaters, and block heaters on the engine.
