Glad it looks like you're at the end of the issue. I've found a few things that affect black tank performance..........if you can call it that! 1st.....forget about the sensors, as mentioned, they're a sails pitch and will need constant cleaning from jet pressure to even be in the ball park. 2nd, make sure you figure out your "water to solids" ratio. Meaning make sure you're not concerned about conserving water that there is not enough water to help disolve/break-down solids and toilet paper. 3rd, make sure you're dumping on a reasonabley level or leaning to the dump side surface.
On the "water to solids". When we boondock, DW and I go about 7 days and the 32 gallon tank which uses the sealevel gauge system is about 50-60% full. Be careful with TP. the tank then get sloshed around till we either get home or to a dump station (usually home). Doing this it does require the use of the tank rinse system to clean the tank, but we've never had any other issues. Even with 4 adults and 2 grandkids we can go a week before filling the black tank.
