Mine was overfilled accidentally year 1 before I realized the sink flows into the black as well so at least it was clean. This happened as I was running the water to drain anti-freeze. I cut an access hole in the belly to drain it.
The water did NOT come up the toilet, it overflowed prior so I thought maybe this was a way to NOT flood the trailer.
In any event, if you drain when it gurgles it will be full but NOT completely full and you wont have to worry again.
