I have 4 30# cylinders. 2 in my 5th wheel, and 2 full on standby. I have a Marshall MEGR-253 regulator that I replaced a couple of months ago with new. At the moment, I decided to turn one cylinder off. This way I will know when it runs out, and it will be a matter of turning the full tank on, and replacing the empty one with a full one. I am trying to keep track of how long each tank lasts. I started a chart for this purpose. I have thought about putting a scale in each compartment for the tank to sit on, and wire the display to a long wire and mount inside where I can see it. The weight should keep me informed of the tank status.
That will work fine as long as you are willing to risk running out at night.
I think you will get bored with it and just check every morning and replace upon seeing the indicator.
