I have a Marshall 254 auto changeover regulator on two tanks. The regulator is set up in such a way that the indicator on top of the regulator will be green if both tanks are open. When the tank that is being used runs out of propane, it will automatically switch to the other tank and the indicator will turn red - indicating that the first tank is now empty and needs to be refilled.
The problem is that you wont know if it is empty and the indicator is red unless you check the colour from time to time. If you have a rough idea of how long one tank lasts with normal use, you could start checking the indicator colour.
Another problem is that not many people know about this indicator and where to look for it. It is not easy to spot or to see what colour it is. It is located at the very top of the assembly and appears to be in a clear, plastic dome/knob shaped housing.
It is probably best to use whatever system works for you. One tank open, the other shut OR both tanks opened and rely on the auto system.
Marshall puts out a handy and informative little booklet called "What You Should Know About Your LP Gas System and its Proper Care". You might find this online or pick one up from a Propane dealer or a propane/gas service retailer.
