Mystery chemical smell
Good afternoon, I have a nasty sticky salty chemical smell coming from the underbelly of our 2017 Freedom Express. It has the underbelly cover. I first noticed this strong smell coming from the fake fireplace cabinet. Very strong. But the smell also comes from any cabinet open to the floor/underbelly. Any cabinet with pipes that have holes around them, stinks. I can also smell it from the outside. If I pull the belly cover away the smell is strong. There has been no water seen coming from under the rv. The belly cover has no sag. The entire RV smells so bad I cannot be in it. Worse with hot weather for sure. Stuck my nose in all sinks and toilet, no bad smell. It doesn’t smell of mildew, doesn’t smell dead, doesn’t smell like sewer, doesn’t smell like sulfur or rotten eggs. Doesn’t exactly smell like straight chemical either, it has a little funk on it. This is a smell that will get into your clothes,etc so you stink having been in the rv. Also of note, the a/c cuts the smell a bit. Pressure or the cool air? I am going to seal up all areas I can for now but I’d like to pin this smell down. Oh, smelled the foam stuff they use to seal around pipes,etc. not it. The material used to cover the belly doesn’t smell. Thank you for ideas.
