Haven't found an easy/accurate way to determine the level of the propane in the tank BUT you can tell which tank is empty by tapping on it with a hammer or screwdriver. The empty tank will have a much higher pitch sound and, of course, be much heavier if you try to lift it.
You can also pour hot water over the cylinder in question and feel for the cold line.
Or, loosen the hold down bolt and lift up on the cylinder in question, and if it feels "light" then it's low on propane.
I always open BOTH cylinder valves when I go out and have the lever pointing to the tank I want to draw from.
That way, it will automatically switch over in the middle of the night if that one cylinder runs out..
As long as you CHECK the status of your tanks on a daily basis if you KNOW you are using a lot of gas, you will be fine..
You just need to check it.. I have heard folks will not open the other cylinder so they know when it is empty, then switch over to the other cylinder.. Why do that when it can do it automatically?
I don't winter camp, so I know my rigs gas consumption and I have often come home and found an empty tank, but the auto switch over worked as designed and I just replace the empty cylinder.
Good luck!
