I live in a mobile home and have been getting this horrible musty smell from my floor vent.My furnace is in a hallway closet and on the floor is an open space for air to come through and that's where I smell it.Can't see any water leaks under sinks or floors and no puddles under home. Also that smell is close to my bathroom.Also took a small pc of paneling off wall that leads to tub pipes but couldn't see anything. Don't want to rip apart all underneath trailer to find something.
