How is the 4" piping attached to the tank. I can see a hose clamp.
Yesterday I tipped the MH for a good dump, When I opened the dump door, there was Black water already filling the compartment, flowing from the tank connection area .. I didn't get a good look, it seemed that moving the big pipe made it worse .. I'm thinking of the worse, something broke like the tank connection .. but today .. I don't see the problem .. guess I'll add water & see where it's coming or going..
We had a very cold winter in NC .. the light bulb didn't keep a big 2" ice cycle from forming from the water bay to the ground. I never liked the way the bay was setup originally so I modified it. Much better for my problem yesterday.

Does this make sense to anyone?
