I have a 2012 Landmark San Antonio. I noticed water leaking from the belly of the coach. A drip from the door-side, just behind the battery box and a larger drip from the roadside, near the kitchen sink. I think the roadside dripping is going to be the kitchen/gray tank 2 however the door-side I'm not sure of. I think it's gray water as well, not waste. There is quite the odor which is making it's way into the coach via the vent in the bedroom steps.
