Cut a large circle in my floor and here is how a M/H is built. Starting at top its vinyl flooring, not glued 100%. Subfloor is OBX but a special order using lots of insulating foam glued in the wood chips. Makes for very light and strong material per sq. ft. but does crush in areas of high traffic and allows for depressions and squeaks, mine maybe 5/8" thick. below that is transverse girders and square tubing running fore and aft. With sheet metal dividers there is about 4.5" of foam. On the bottom closing plate of Luan plywood covered with a woven black waterproof cloth. Sure the floor is glued and rolled prior to install on the chassis. Roof is similar, walls same but thinner.
Have read where someone has excavated in bad area and injected expanding foam to fill soft area.
