I'm having a similar problem with the black tank on my brand new X23b. I believe it's because the tongue height is slightly high, and the black drain (and sensors) are on the front of the tank. When I dump, the tanks read empty, but as soon as I decouple and level the trailer, it says the black tank is 1/3 full.
I cannot lower the tongue of the trailer. So...I plan on the next trip to drive the camper up onto boards so that the rear is slightly higher than front. We'll see what happens in 2 weeks.
