I have a fleet wood prowler 5th wheel. The roof appears to be leaking in the closet. I opened a small area of the closet up and the wood bracing I see is soaked, but appears sound. We first noticed the leak, because the closet carpet was soaked. We plan to fix the roof leak as soon as we can manage. Will we also need to completely remove all the closet wall? Will the wood continue to decay unless the wall is opened up? We live in an area of low humidity.
