12 volt dehumidifier

Thanks to all. Living in the Smokies I am familiar w/ humidity. I have 2 units in my home as well as a large "commercial type" in the crawlspace of my house. It looks as though I will have to stay w/ my current practice of using 2 large "Damp-Rids" and changing them every month during the winter. The RV park where I keep the TT cuts off power/water to the section of the park where I am during the winter as they don't rent spaces in that area during the winter. My TT is one of only 2 -3 that remains in storage in that part of the park during the winter. This park is convenient, close to my house and from April thru Oct I have access to water, elec and sewer. Cost is reasonable but just went up $10 this year. I may look around for another spot where I can have and use the electric all year long.
