So i’m working on a 1999 Coachman class B with a fiberglass top and want to post it for some outside thought. There’s a piece of wood that is fiberglassed into the fiberglass ceiling probably for support and mounting and it came like this from the Coachman factory. Before i bought it, it already had a leaky vent and already had damage. Now that i’ve fiberglass patched that same vent hole, want to know what to do about this damage inside. Here’s 2 pictures of the damage and a picture of the other identical side to compare it to:
It looks to me like the water from the leaky vent got all up into that piece of wood and got locked inside. Now it’s definitely not ideal, but could i just leave it there and use it like i would to build the ceiling? Or do i have to remove it and replace it?
