To be honest, I've never really taken the cover off the tanks. I just open the top flap and open a tank. I've never seen the changeover window.
When you open the flap to access the valves, look between the tanks and slightly aft. You will see a lump of clear plastic with green or red showing underneath. There is also a white plastic knob with a pointer.
If the pointer is set to a tank with fuel in it and the valve has been opened properly, the indicator will show green. Once that tank is empty, the indicator shows red.
With both tanks open, the tank that is pointed to will be drawn from exclusively
until empty. Then the other tank will be drawn against.
It is your job to flip the pointer to the other tank (indicator will switch to green) then fill the empty tank.
Repeat as needed for the rest of the life of the RV.
Never run out. Theoretically, never have flashing lights on the fridge. But Reality has other plans....
