I still don't understand my propane situation. Any help appreciated.I have a "76 lb tank" which I take to be "full" at 80% or 61 lbs. I am used to having two "30 lb" bottles, but when they get filled I am charged for typically 30 lbs, and they are only filled to 80% as well?So it seems my "76 lb tank" is about the same as two 30s in real life?As an example my first time to refill the tank it was showing about half full, and they put in 26 litres to fill it. I got charged by the litre for the tank instead of by the pound as with cylinders.My Manchester hand- out says 4.24 lbs/gal (US gal no doubt) and that would be about 3.8 litres/gallon? so a 30 lb cylinder would be about 27 litres which is about what they put in my "76 lb" tank at about half full, so I am thinking all I have here is a sideways two 30 lbers same as I had in the 5er.Is that about right? Or how do you figure propane amounts?I also don't understand the "liquid propane" deal, where I had to go to a sort of gas pump that did propane to fill the tank instead of to the usual cylinder fill place. Don't cylinders get "liquid propane" too? But they charge by the pound to fill a cylinder, but by the litre to fill the tank.

Yes, I gather there are two sets of rules in the States for that so they can do either lbs or gallons. When they fill an empty "30 lb" cylinder by the gallon, do they put in 7.2 gallons as the 80% "full" ? (Manchester says 7.2 gal per 30 lb cylinder)My 76 lb tank should be 17.9 gallons at 4.24 per. Does that seem right?

Our brochure for our Class C states a Propane Capacity of 17.5 USG or 66 Liters. Liquid Propane density is about 493 kG / 1000 Liters.66 Liters would be 32.54 kG or 71.6 Pounds.

around here they charge by liquid volume for filling everything, bottles or frame mounted tanks, i haven't pay by the pound in at least 20yrs, even when travelingframe tanks and bottle have different fittingsmaybe there is a regulation regarding who fills what up there in BC ?yes, even bottles get liquid LP 'pumped' from the 'tank' at the place of fill upis your tank marked in pounds, or in water volume gallons, my tank is is 24.0 gallon appox 100#, my last fill up Sunday the 10thwas 21 gallon, i was not dead empty, the fridge was still going up till the moment i turned if off and shut off the tank

I have not seen a size of the tank on it, but can look next time it stops raining! The MH brochure says it has a 76 lb tank. If they use different temperatures as the "standard" for tank size, I suppose that would explain minor differences in "sizes"I somehow thought I now had a huge amount of propane compared with before at two 30s. Maybe not? Same as?Actually, I only think he said it was 26 litres. After he filled the tank he looked at at the pump numbers, then went to a little terminal beside that and tapped in a bunch of numbers, and then that spit out a slip of paper, which I took in and the cashier did something or other, and it came out as $26 on my Visa. Propane is about a dollar a pound but it is also approx. a pound per litre so I don't know. I was not paying enough attention obviously. Next time for sure!
