Beating humidity

Last year for the first time since I bought my gilder I discovered
what cold, humid, Northern California winter air can do to the
untreated steel parts on my glider. This year I was determined to
keep corrosion at bay and bought a dehumidifier to put in the
trailer. I also bought one of those radio-remote temperature and
humidity sensors to put inside the trailer to keep track of the
effectiveness of my efforts.

My Cobra trailer is pretty well sealed except for a gap between the
tailgate and the fiberglass top. I positioned the dehumidifier on the
trailer floor between the tailboom and the wing and sealed the air
gap. I checked after the first week and discovered the dehumidifier's
water receptacle was about 1/3 full. The past couple of days have been
rainy and cool - low 50s and 77% humidity this morning. Inside the
trailer it's a few degrees warmer and the really good news is the
humidity is 22%.

I'll probably do a couple of experiments in the coming weeks to see
how long it takes to get the humidity down and how long it takes to
drift back up to ambient levels with the dehumidifier of. I know that
not everyone keeps their trailer near 110v power outlets and my
dehumidifier is 330 watts, so batteries with an inverter and/or solar
cells are not an option for continuous operation, but maybe it would
work if you could get things dry in a burst and let the trailer sit
for a period of time before giving it another burst.

Here's the dehumidifier I bought:
