Since at least 2004 Winnebago has been using the TrueLevel external sensor system. Guess what? They are still inaccurate because crud builds up on the tank walls and fools the sensors. The Garnett SeeLevel is considered by many to be the best out there and when enough crud builds up on the tank walls it also quits indicating properly.

If you have a straight shot into the black tank from the toilet, shine a light down there and see if you're empty and just forget about the sensors. Worrying about such things while relaxing defeats the purpose of having an RV.
If you cannot verify that the tank is empty, then the Geo Method works as well or better than any magic pixie dust that Thetford produces.
Mark this day on your calendar folks. I agreed with SoundGuy 🙂

Newbie question here, on my 5th wheel the instructions say to never run the black tank flush with the tank dump valve closed. Am I missing something?

Please let me know how to trouble shoot this.
I have tried several type of black tank cleaners and this is my favorite:
https://www.amazon.com/Kronen-KHT003-Handle-Holding-Treatment/dp/B00BFTZC3A
Pour some that down into the black tank and let it slosh around. When you pull into your next destination, dump black and see if that fixes the false positive.
If it does, use the holding treatment regularly and especially make sure some is in the black tank as you travel to slosh it.

I've had the same issue. I think that this was $14 but worth every penny. I understand that Camco has newer one with a spinning head on it. Go with it from here on Amazon.

Simple answer is... If you want a reliable monitor, get an external tank sensor. Not hard to install. 100% foolproof

Fill the tanks roughly 1/4 full and add about 1/2 cup or so dishwasher soap (liquid) before you leave for next trip. When you get to the site, dump the tanks and most likely they will work. I've tried other methods and this by far works the best for me. The dishwasher soap is made to dissolve the grease and sludge that's grounding the sensors. I also do this every 5th or 6th trip as maintenance cleaning, have not had a sensor give a false reading in 5 years of doing it this way. Good Luck !
