Actually, is the OP talking about storing the RV or while he's using it? I don't recall that really being stated??
My first post was assuming he's storing it.. But, by the sounds of some other posters, they are in it?
Anyway, I don't use the Dri-airz things when I'm using it. Just when it's being stored.
There was a comment about leaving the vents and windows open while using them too.. I don't open any windows, just crack the vents a tad. I've left them closed and it started to get a little "stale smelling" in the trailer. Not that 'damp' smell or anything.. Just "stale".. When I crack the vents, it goes away. That' my story! :)
