Campers and RVs that are left unused for a long time can start to smell funky inside. One common stink that can hang around is a fishy smell. This, of course, happens after a successful fishing trip, and the odor can stick around even after the fish is gone. Getting rid of the fishy smell can be a real challenge, especially if it's soaked into the upholstery or carpet.

Another usual odor that can pop up in stored campers and RVs is a musty or moldy smell. This occurs if the vehicle wasn't properly dried out before being put away, leading to moisture buildup and a cozy environment for mold and mildew. The musty smell isn't pleasant and can be tough to kick, needing a thorough cleaning and airing out of the vehicle. On top of that, other smells like cooking odors, pet stinks, and cigarette smoke can also stick around in the camper or RV over time. These odors can be quite stubborn and might need some serious cleaning and deodorizing to fully get rid of them. It's hard to both seal it against the elements and still make sure the space is well-aired and keeping it clean regularly can help prevent these odors from setting in and hanging around in stored campers and RVs.
