I wonder what Gaslow's advice would be.
So what do you do when they both run out at the same time??
It was recommended to me that I use one cylinder until it was empty and then change to the second cylinder, with the gauge. Fill up at the next available opportunity, which fills both tanks.
You could of course put a gauge on both cylinders. Important to note the gauge only registers "getting empty" when it's going through the last half of the tank. So it stays on green (full) for a long time, then suddenly and quickly heads towards the empty mark.
