.... and besides, I know precisely when my propane tank needs refilling ....
I add the number of times I've gone on 3-12 day trips per "camping season"
... and I always get the same result = I need to fill the tank every 2 1/2
years. Works every time. I've never run out of P. ;>)
But, I am adding another Manchester under the sliding door ... not so I can
go 5 years between fills, but so I can camp more in winter and run the
Carver.

As Al said .... it's fizzix.
