The Casitas also have fiberglass on the bottom, wood over. It is all good until you get water inside like from a burst water line or a leaking window. Then the water is trapped between the fiberglass bottom and the wood floor.Our Trillium is fibreglass on the bottom. Wood inside but fibreglass under it. It’s a 74 and no leaks anywhere since there’s nowhere to leak.
Not sure how others are built.
