I have a 24SJ Thor Citation on a Merc Sprinter chassis...would mine be the same configuration?

Correct the black tank gets stuff from the toilet and bathroom sink. Here's the fun part, when the black tank is full, it backs up in the bathroom sink. Make note to yourself, don't set your toothbrush in the sink. Today I was flushing the black tank from the last trip. Closed the gate valve to get some water in it to help the flush but I'm staying right there watching the level when I hear this water burp. Go in the bathroom and there's water splattered around the sink. Apparently as the black tank filled, pressure must have burped up the sink P trap. That doesn't give me much confidence in the tank vent.
