Yes the black tank sensors are notoriously inaccurate. I can feel your frustration and can even imagine doing the no hose valve pulling myself. :) But before I did that I would open the toilet flush valve and take a look down into the tank as that is a much safer option in my book. :BThese tanks are typically not deep but rather long and wide but fairly shallow. So the tank bottom you see under the toilet is only about 1/2 inch shallower than the center of the tank.
Before I started dumping too many things into the toilet I would probably just fill the tank up with water from a hose and let it sit for a week and then drain it. But I am able to drain my tanks at home and this might not work for you if you cant.
But if you can drain at home try this.

- Fill the tank full.
- let it sit for a week.
- hook up the drain hose and pull the valve for about 5 seconds then close it again to lower the level in the tank some so it can slosh around.
- Then go take the trailer for a drive around the block or to the campground.
- Drain the tank fully and check the sensor.
