Just so you know, if you use blue rhino you won't get a full tank for your money. They are thieves and have been sued for it.

I have my own propane filling station and have NEVER been able to get anymore than 3.5 gallons (yes, I know weight is more accurate)in a bottle that's supposed to hold close to 5. $20 for a 3/4 full tank is outrageous...

the tanks are supposed to be filled by WEIGHT! the reason for that is so there is room for the propane to expand inside the tank as the temp goes up. there is both liquid and vapors inside the tank you have onboard. the expansion rate from liquid to vapor is over 270 times. that means one cubic foot of liquid will be over 270 cubic feet as a vapor. if you do not allow the proper vapor space inside the tank will overpressure and can fail. there is a empty weight and a full weight stamped on the handle. the full weight should be around 80% capacity of the tank. ignoring this can cause fatal consequences. I have seen what a 20lb tank will do to the cab of a pickup truck when it fails. if inside a compartment of a trailer it will destroy the trailer!
