Ok, probably a real basic question. I have a M18 with 2 propane tanks. There is a tab on the regulator between the tanks that says "source" with an arrow pointing at one tank. Does this indicate which tank the trailer is drawing from? If so, does it swtich automatically when one tank is empty?
I ask because I have used my trailer for 10 nights so far which have all been dry camping. I haven't run out of propane and the tab that says source has been pointing at the same tank the whole time. I am just curious to know if I am still on the first tank, or if I may suddenly just run out of propane without a warning of having one tank empty. I really have know Idea of how long to anticipate a tank to last at this point.
