Question Sewer gas smell

[Seef]

Sewer gas smell at different times under bed on our 2020 294RL, not using washer/dryer connections and drain cap is in place, any ideas?

Do you open all tanks at the same time to empty them?

We had a leaking check valve in the back of the Macerator toilet and I believe gases were traveling through the cabinet/wall to the bedroom. I found this because I removed the toilet to clean out something that shouldn't have been in there Haven't noticed it since.

Also, "RV Digest It" Is the best product I've used for holding tanks. It does take some time to (normalize) tanks that have been neglected. But it passed my wife's standards. She can smell a beer on your breath from last week
