Sewer smell in bathroom
I have a sewer smell in the bathroom. Toilet is holding water just fine. We have cleaned the black tank and grey tanks several times. Vent being closed or open doesn't seem to change anything. What if...

How about checking the vent cap on the roof? If you remove the cap on the roof you may find that bees or something is blocking the vent with a nest.
Or that the pipe coming up through it isn't too tall and is sealing against the underside of the cap.
Good point because during the plumbing process they drill the holes thru the roof a bit on the large side. With the vent cap it seals out the rain but under the vent cap the large hole lets sewer gas back inside the cabin.
Remove snap cap and seal around pipe under vent cap.
