Please help me! Yesterday, I needed to fill the gray water tank, so I can flash the small gray amount of water before we head back home. Long story short, darn drain plug! I didn't pay attention...
If you can take down the underbelly material, at least partially, you will see how much water is in there. Leave it open and run a fan to dry it completely. If you find a large amount of wet insulation, it would be best to remove it and replace.
