We bought our camper used, but we do not use our bathroom. It didn't smell when we bought it, but we prepared it for travel. The first week we had it at the lake it started smelling. Why?


If you remove the fluids from a sewer tank, bacteria will grow in it and start to smell. You need to clean and sanitize your tank as per the directions in the article and always make sure there are some enzyme chemicals and water in it, even if you don't use it. That should get rid of the odor.
