Hi Phil,
No, the first 0.8 is how much propane they will put into a tank--i.e. if it is a 20 gallon tank--they can only put in 16 gallons. The 2nd 0.8 is the efficiency of the furnace. So of the 16 gallons available only 12.8 end up as heat inside the rv.
I filled up today--and it was so cold that the propane was liquid. I'd not seen that before. It looks clear like water.

Don,
Thanks for your propane data!
It looks like you have about the same size propane tank on board as we do - 18 gallons gross - so I was curious as to about how long ours might last in an extreme cold situation with around the clock usage. (However, our Class C is a bit smaller than yours.)
What's the purpose of your "1031952 x .8 = 825561 inside the RV" calculation?
Didn't you already account for the 80% efficiency of the furnace in the line above that?: "21499 x .8 x 60 = 1031952 btu's for the tank size"
