I had been tracing this problem for over a year. It got bad on bumpy roads and I presumed it was bouncing the water out of the p-traps, especially the shower. I would refill the p-traps & it seemed better but continued on rough roads. I discovered a vent check valve behind a drawer in the bathroom next to the shower. Sure enough the check valve was bad. Unscrewed it & screwed another on. Problem is now solved. I hope this may help someone else who is having a similiar problem.

We had a similar problem but it was from the BLACK tank.
After 3 attempts at CC service with no improvement in the problem, Carriers & Sons found what was wrong. Take a guess. The black tank was never vented through the roof to the outside.
Yuk!
