We had a similar problem with sewer smell and I thought it was water in the trap but it ended up being an intermittent air valve that is on both the sink drains. I didn't even know we had these air valves. They are spring loaded valves that allow air to drawn in under vacuum (when water is going down the drain) and the plastic flap or spring ages and it no longer seals properly, allowing the tank gasses into the RV. Yes, these gases permeate down into the storage areas and below the RV. I was searching for a crack since the stench was strong in the basement and underneath the RV. Replaced the valves and it fixed the problem for good. Keep this in mind if the stench comes back. Ours would happen intermittently.
