The idea of using rock salt intrigued me, so I thought I'd ask around to get other thoughts on the idea.
I use DampRid when the trailer is all buttoned up, in storage, and only get about 1/4 cup a month in damp weather when the temps fluctuate quite a bit.
I have used electric dehumidifiers in the past when I had electric available, while the trailer was in storage, and when I didn't live in Ft. Worth.
Here, there seems little or no need for dehumifiing.
Still I thought that it might be interesting to hear some other thoughts on the subject, as I might move to another part of the country someday and could pull this info out of my head if needed.
So, what you guys are saying is, forget the salt idea.
I hear you, and I'll just file it away under nonsense, in the dark corner of my gray matter.
