Anyone tried these? Dehumidifiers

[TXCarol]

Hi all,
Just wondering if anyone has tried these when storing their RV: http://www.h2out.com. I read about H2Out in this months FMCA magazine. I've been using Dri-Z-Air, but am thinking there has to be a better way. I don't like dumping all that salt water that's left behind. And here in Texas, with all the rain we've been having I'm going through a lot of crystals (which work very well, by the way - no dampness at all in the RV or storage bins). H2Out has received good reviews on Amazon. I like the fact they're renewable and green (although they are a bit pricey). Any thoughts? Thanks, Carol
