My apologies, like others, unless I buy a pre filled tank, I've always paid by the gallon, in many states. Didn't know some parts of the country gouge for propane.
In your case all of the options mentioned will work.
I have very rarely paid by the gallon. The places i frequent most have a sign posted as to what they charge for say 20 or 30 lb. Way it is. So maybe that is why the op is wondering how much is in the tanks. I got the same thing going on. My camper has been in the barn since this spring and since I am older than dirt, don't remember for sure what my tanks status is since I turned them both off when I backed it in the barn. The flat rate is OK with me if that is what is posted clearly. I don't see how that can be gouging if you have a choice.
