So i need to replace some damaged floor about a 2' x2' area under the vanity and back corner of my shower. I know the flooring is made of a thin wood base with foam board topped with 5/16 plywood. I want to know how the metal base/joist framework underneath is laid out. Is it a 12" square metal grid base or something similar? I want to know where to cut so I can reach solid metal. I can seem to find any Winnebago drawings for that.
