My black water tank gage always shows 2/3 or full even though I've emptied it and flushed it. What would cause this gage to not read accurately? and how can I fix it? thank you
I consider the tank gauges as more of guidelines rather than rules.
Most campers are setup so that the toilet drops directly into the black tank, so you can just shine a flashlight down there to see how much room you have left. Remember that a lot of the tanks are wide but very "shallow", not very deep - even if it looks almost full, it may be only half full.
With experience you'll figure out how your tanks should look.
