I have a meter on my freshwater fill hose.
From empty (pump cavitation, making unusual noise) to full (water running out the vent at the back of the rig) it averages 42 gallons.
Normally I get two freshwater fills, then I have to dump (black tank is full when toilet burps when flushing).
I gave up looking at the lights except for the freshwater tank.
