Had the faintest odor of sewer tank in my RVbut only after traveling. Research online says it might be an air leak... so here's me fixing a leaky roof vent. A simple project, but it worked perfectly and now my Airstream is fresh as a daisy once again.
The vent is made by Ventline, which is owned by Dexter corporation. It's a standard RV item, so I suppose you could replace it if you wanted to save yourself the 30 minutes of repair work.
