Lexington 2011 floor water damage

[Hogan3503]

I have a 2011 Lexington GTS 265 with some water damage in the floor. After removing the linoleum, it looks in the living area from the back of the cab seats to about 3.5 feet will need to be replaced. Can someone tell me how the floor of this model is constructed? I see the plywood, then looks like styrofoam, then is there more plywood? Underneath the motorhome all I see is full metal sheet covering entire floor. I will have to investigate more to find out how far from side to side and where the leak is coming from.
