Run the AC or not?

So there are lots of people who leave their RV stored in Florida during the summer while they retreat to the north to avoid the heat and humidity. But what about the RV, is it ok not to keep at least a high temp setting of 85 degrees or there about to minimize moisture inside and prevent mold and mildew? 

I would love too hear everyone’s opinions on this, cool the rig to avoid problems, or just stock it up with kitty litter and other moisture tapping stuff in hopes to avoid excess moisture and mold growth.

Cool or not to cool.

So the climate plays a role in this also and how good your seals and gaskets on the RV are also play a role in this picture. If everything is in good condition and fairly new, then it may not be such a big deal, but when you aren’t around and it’s closed up, do you really know how good the seals are? 

Yes it also depends on available power to run the ac and your budget. So that aside, what would you do, do you have any stories to share?

Really like top hear from you!
BTW my opinion is if I could afford to leave a rig stored in Florida and be someplace else and I had power to it, I would run the air to preserve the condition of the unit as best I can and minimize the risk of damage and expense of getting rid of mold!

  1. Definitely run the a/c. Or, install some sort of dehumidifier and check it daily/weekly.
    Humidity will destroy the lightweight wood products inside campers and coaches.
    Before going full time, I used to store my class A at a place that had 20A service for a fee. I set my middle a/c around 80* so it would run during the heat of the day and rest at night. Conversely, I would set my heaters when it got below freezing to avoid having to winterize. But, Nashville doesn’t stay cold very long.


  2. Hey Rick. What do you think the ideal temperature is to leave the thermostat set at?You mentioned 85F in this article. I left mine at 80F. My friend in Jacksonville leaves his home at 72F.

    1. I would recommend between 80 and 85, either way it will keep the moisture down and not cost a fortune to do so.
      The Big Idea is to control moisture in the rig to prevent mold, mildew or warping of wood etc.
      A small humidifier is one solution, but it must have an automatic drain system on it which can become clogged or the pump fails. Depends on the unit and design as well as cost, in general they are an air conditioner that produces heat as well as cooling in the process of extracting moisture into a tank that needs to be emptied somehow.
      Roof top ac units are typically simpler to manage and reliable enough to do a good job.

      All that to say that 80 degrees is a reasonable temp and helps maintain the environment inside the rig very well.
