What is my gas tank size?

[kirkndopp]

Without getting wet and dirty while climbing under my bus to measure out my tanks - does anyone know where I can find out how big my gas tanks are? The bus came full and we're wondering how far we can go before they are empty? The guy we bought it from said 150 gallons but we recently put some gas in it and it seemed like maybe he was wrong. It's a 40 foot bluebird 1989 diesel. thanks.

I saved the above link to my desktop. It is how we figured out our fuel tank on our BB. I think we figured it had a 90 gallon tank. All I know is David only topped off the tank a couple times (fuel gage wasn't working) on our way out west, whereas I filled the Class C up daily.
