    Holding Tank Level Gauges

    All three of our waste tank level gauges seem to have become completely inaccurate. Reading 1/3 or 2/3 after a complete empty. How do these things work ? I have read about different tank cleansing processes to make them work. Are there more robust sensor systems out there that will give reliably readings without complex cleaning processes ? It would seem that somebody would have figured this out . . .

    I had to replace the black tank on my last 5th wheel and I added the Horst probes when I did it. They did work well. They are super easy to install, just pull out the old ones and insert the new ones and reconnect the wires. The issue is getting access to the tanks and that means dropping the belly cover. Not much fun. I won't be upgrading my probes unless I need to access the belly for something else.

    I don't worry about the actual tank monitor reading...after you've camped in it for a while you determine the tank capacity in terms of # of days normal use.

    X2. Even the tank monitors on "high-end" units such as DRV get dirty and quit telling you a true story (and it's that they get dirty - not fail). Many long-timers/full-timers just learn how long they can go or how many showers they can take before needing to dump. It took us a while to get comfortable with it, but we've gradually gotten up to where we can go almost a week without dumping (showers and dish washing with the gray tanks are more of a problem than the black tank).

    You will also find that they don't register "real time"......when you empty them they seem to need to dry off before they read empty
