Thank you all for your input. We are gone up North for at least 6 months, so a chemical that needs changing would not be practical. The windows being open is an option that is very good and would work, but I don't know if during a hurricane if it would be feasible. The dehumidifier is also a very good suggestion and would work. Does anyone have actual experience with either method, and if you use a dehumidifier, what brand. It can be drained into the shower, but would have to have an automatic feature of turning itself on after a power outage. Also, would the filter, if it gets dirty cause it to shut down? Unfortunately, it would be either of the two methods. Which one is best? By the way there was no leaks in the RV. The mold was on wood in cabinets and on the wood fridge surface, and on belongings.
