I found your post, but we have no leaks under the trailer. The tanks are out in the open on mine. I've been under mine several times to push up on the bottom of them (they're a little droopy) in order to get the rest of the water out. Never saw any signs of leaks on either tank.
Now I've noticed sometimes when flushing the tank, I can smell the smell outside the trailer. It's odd too, because what we're smelling doesn't smell like the grey or black waters' usual smell. This is like a stink bomb; it's really sulfury. Almost like being near Mammoth Hot Springs in Yellowstone NP. And I only smell it around head level when inside the trailer, not near or under any of the drains, sinks, or cabinets. Definitely not from the grey tank, and flushing the toilet does not bring out the stench. I'm beginning to think something came disconnected in the vent pipe.
I'm at the point where I want to start tearing into things because the surface sources aren't looking like the culprit. But I'd really like to get my hands on some design plans for this trailer since I want to work in the right places, not guess and create new problems.
