I had/noticed the exact same issue in my '05. Saw some staining from the inside and thought the outside was leaking. When I removed the inner panel I found rusty screws and staining exactly like what you have. Like you I could not find a leak after hosing or a hard rain.
I determined that when taking a hot shower, steam must travel up and past the inner panel (since there is no gasket) and condense on the skylight lens. It then gets trapped there and was causing the staining and a some damage to the wood along its edges, but fortunately it's minimal. The softness extends maybe 1/4" in from the edges.
Based on this, I applied a thin film of tub and tile caulking along the edges of the wood to help repel some moisture and seal them. I wasn't too worried about the foam as it wont absorb water.
When I posted about this problem, another member was quick to point out that I had nearly a 10 year old trailer, with this very small amount of moisture issue. Because it was such a small problem, it would take another decade or two before this was really a problem. By then surely something else would be a MUCH bigger deal.
