Flood! What now?

I had the same thing happen to me. I rented a carpet cleaner and using only the vacuum wand we removed water for 8+ hours, way more than 5 gal. When we stopped picking up water I set the AC to 74 degrees (too hot and mold will start forming, too cold and the water does not evaporate as well). I put a large barrel fan in the hall and purchased the biggest dehumidifier I could find 65q/h. The firs hour or so of operation we filled the dehumidifier's almost 2 gallon holding tank. That went on for almost 24 hours. As I remember after 24 hours it took about 6 hours to fill the tank. We ran it like this for 2 weeks. Measuring the humidity over the two week it went from the upper 80's down to 26%. 26% is about as good as you will ever get in Florida on a summer day. I remove the fan and left the dehumidifier in there until winter. As part of our normal routine we run the dehumidifier all summer long.

To get the water out of the padding you must reduce the humidity low enough it wicks up through the carpet.

Forgot this part: I opened every access panel possible, my slides are flat to I put stuff under slide out carpet where it overlaps the coach carpet to ensure air was getting to it.

I was very lucky no apparent damage but you have to jump on it before the mold starts. If the mold does start call a carpet specialist. They have stuff that may kill the mold.

good luck
