Insulation under pass through

[Bgribb]

So last weekend while setting up at a local campground. I flooded the camper. The toilet overflowed and the water ran to the front and out through the pass through storage. We have a rockwood mini lite 2509s with the murphy bed. So with all that said, while I was inspecting the camper from underneath, I discovered that the insulation under the pass through is soaked with water. That front area of the camper is covered with a cloth like material. I cut a small hole in the cloth and found the water soaked insulation. So my guestion is. Does anyone know what is in that area of the camper? I want to cut a flap in the material and pull out the wet insulation and let it dry then replace the insulation until a better fix can be done? I saw some wires running up to that space, but just wanted to make sure nothing else real important is in that area. Thank you for any info.
