19FBS stored, no power and Houston humidity

[CPC659]

We store our 19FBS in a spot that has no shore power available. We live in Houston, TX. The average humidity here is almost 82% and soon it will be higher than that. Often. We have DampRids inside, they are drawing moisture. But I'm concerned they do not draw ENOUGH. I am using a humidity gauge to track how effective they are. They seem to have difficulty dropping the humidity inside significantly when it's hot; > 75 degrees, and when it's very humid; > 75%. For more than half the year Houston exceeds both those temps and levels of humidity. My understanding is it's best to keep it well below 60% inside. Any tips? The DampRids may work great in other less humid locations, but we have no plan on moving. LOL. Are there areas I need to look at where moisture entering can be minimized? Like under the bed by way of the passthrough maybe? ALSO, if you live in an area as humid as Houston, do you leave vents open or closed in humidity like this? I've seen arguments for both but right now ours are closed. Any suggestions would be greatly appreciated. TIA

How about using a solar powered ventilation fan?
Like this...but no longer made.

Any link or suggestions for one that would fit? LOL. Did not notice the one you just provided. Thanks again.

I linked the one I found but it looks like they do not make them anymore.
Could be others with a little google searching.

Get a 100 watt solar panel, then you can power most of what you need. Use a rectifier for low draw elect. How often do you go to check on it? You may be able to power a small dehumidifier. Put the output in the sink.

I have 2 large Eva Dry desiccant type dehumidifiers in my 20' trailer since the fall, I'm not impressed. They generally can't lower humidity below 58-61%. Luckily I am parked in my driveway at home and can plug in. As soon as temperatures warm up enough here, I am plugging in my 30 pint dehumidifier.

BTW, here's a good link for a calculator that shows you the relation between temp/humidity/dewpoint and risk for damage or mold at various levels. You just use your cursor to slide the temp and humidity levels up or down to see the relation.

As for venting, I'm thinking you would allow more humidity in by doing that. But during hot weather, it might be important to vent to keep interior level from rising way higher than ambient temps.

Here's the calculator: Dew Point Calculator

OP, what did you decide to do?

I'm also in Houston and the Flagstaff Micro lite 25DS we are getting will have to be stored in a storage yard, and I'm a bit concerned about the heat / humidity (especially after the last few weeks).

The lot we will probably be using includes 15 amp power, so we can run some fans to keep airflow, and it's covered so we will probably leave the roof vents cracked.

Aside: storage lots are damn expensive in Houston!
