Sewer smell

We have a second A/C in the bedroom in a Cyclone 5th Wheel toy hauler. When it runs, we get a sewer smell. Anyone else have this problem? It is worse when the tank is about 1/2 full.
Thanks!

I had that problem in my Landmark,found the vent pipes did not exit above the roof under the vent caps. They where short and vented above the ceiling and under the roof.The wind directional vent caps cured the problem.

Had the same problem and it was fixed at the rally. The vent pipe was below roof line and had shifted so that it did not vent out the cap. A coupling and short piece of pipe fixed the problem immediately.
