When you have to switch the tank over at 3:00 am and it's dark and cold out usually helps me remember to fill the empty tank the next day. When the fridge light blinks in the afternoon and I decide I'll refill the empty tank tomorrow or the day after is when I forget to refill. The 2 X 30 lb pound takes take too long to empty for me to remember how much I have used them and when they were last filled.
I leave the valve on one tank closed so that I know when one tank goes empty. The green/red indicator is not visible unless I take the fiberglass cover off of my trailer. I would also be interested to hear how the regulator switch works as well.
