humidity/moisture in storage

Living here in Virginia, where in the summer particularly it gets as humid as it does warm, and with an RV that isn't used continuously, but spends a fair amount of time in both summer and winter (when it is usually a bit less of a problem, but not much), I think I am going to fill the plastic dishpan about half full of calcium chloride ice-melting salt and leave it sitting open in the sink.

I know from my days as a chemist that calcium chloride is an excellent desiccant, and sucks moisture out of the air very effectively. Of course, I'll have to monitor it to make sure it doesn't overflow into the sink, not that that is all that bad an idea, but I do want to make sure that there's enough solid in there to do the job.

At 40 cents a pound for the 50 lb bucket of it that I bought at Wally World the other day, I think that's probably both cheaper and more effective than trying to run a dehumidifier in there.
  • On the other hand, I highly recommend a dehumidifier. But it should have a drain so that there won't be any filled tank issue. Nothing can do the job like a dehumidifier, and if there was power available where I park my trailer, I'd use one.

    It won't be that expensive to run; the inside of a trailer/MH is only a few hundred square feet.
  • don't recommend a dehumidifier since the tray on the bottom is for storage of the water taken out of the air. it will be needed to be emptied every day or so, or it will over flow and leave a stain which will be even harder to get out of the rugs etc.
