I'm so sorry this happend to you. I know that "rushing" sound and I feel your pain. Something similar happend to me at the 2007 Florida Can Opener rally, except my problem was limited to the bath at the back 4th of the trailer and I was there to contain the damage when it happened.
There was no shop vac around, so at others recommendations, I pulled up the carpet in the affected area. It is much easier and faster for the subfloor to dry if the carpet is removed. Then I placed both heaters and fans at full blast to dry the area as much as possible. I didn't have to replace the floor. It's my understanding that, while one incident isn't good for your floor, it is repeated incidents left damp or unchecked leaks that will ruin it. The key is to get everything as dry as possible as quickly as possible.
My advice is to keep the air circulating, fans, etc., even for a time after your THINK it is dry. Air circulation will hinder mildew. Then get a a few buckets of Damp-Rid
from your local Wal-mart or hardware store. Set them around in the the Tradewind. You'll be amazed at how much moisture it can pull out of the air.
