Black Water Tank Removal

I have a 2000 19' Bigfoot travel trailer. I'm trying to remove the black water tank due to a leak. I have it completely uncovered and unstrapped, but am having trouble with the toilet-to-tank connection. Can anyone offer suggestions as to how to proceed?

I don't know about the Bigfoot 19' specifically, but usually RV toilets use mounting flanges just like a home toilet, so if you can find them there are likely two nuts at the base to remove to free the toilet from the tank-mounted flange.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

Brian is correct... my Scamp is a "marine" toilet. ALL parts other than the discharge are inside the body of the trailer. A couple of bolts remove the china toilet from the black water tank (which it sits on, inside the body).

Is it different in yours? Pictures

I have already removed the toilet. It's the drain pipe between the toilet and the black water tank that is causing the problem. I can't see how to either remove it or release the tank without removing it.
