I see no reason to not take advantage of your auto changeover regulator. You check (or should) the air in your tires before a trip, and once a week if you are out for any length of time (we're retired and go for months at a time)...next time you do, check the air in the tires and the gas in the tanks by looking at the indicator. Takes only a minute and by using the auto changeover regulator for what it is intended, you won't run out of gas in the middle of the night, in the middle of the bar-b-que or while enjoying your LPG Campfire in a Can
Check the air, check the LPG; that simple.
