Brett, When driving, I can get rid of the smell by turning on the bathroom fan. When parked, I have to open the door and windows but only if the coach is not been lived in for awhile. The sewage smell is not present while sitting in a campground. howiesfmca

Where does the smell come from if the coach is sitting still in the drive way after winterizing? I can't find a vent anywhere.
