I switch tanks at the switch-over valve when one tank runs out.
That way I know exactly how much propane I have.
Then I just have the empty tank refilled at a convenient time and place.
Easy peasy and it doesn't cost a thing. ;)
It's annoying to have the heat cut out in the middle of the night in 0F weather. Been there a few times, Mopeka sensors keep that from sneaking up on you. But if you don't camp in cold weather, then there are few downsides to just letting the tanks run out and running them like you do.
