How are double wide mobile homes put together?

Mobile homes are built on an assembly line starting with the trailer-like frame coming into the shop. The basic floor joists are placed in and attached to the frame, then runs of piping, electricity and drains are fitted into these joists. A thick strong membrane is stretched across the bottom of the joists and then insulation is place in between the joists and sealed in by the subfloor which is often K3 or chipboard, but can be plywood in better quality mobiles. The walls are all prefabbed and ready to simply be placed in position and airnailed to the floor and each other. The mobile will now move up the line where the kitchen and vanity cupboards and their respective counter tops are installed. Next will come fitting of tub, sinks faucets, waterheater and their respective Plumbing.. Next would be the doors and Windows followed by the roof joists then ceilings and ceiling insulation. Now that workers are finished going through the home, carpets and roof will be installed. -This entire process happens in about two days or less. -

I once worked on a Motor Home assembly line which was much the same but a little less complicated. We built 4 versions of large Motor Homes in about 6 hours each. -Two on GM chassis units and 2 on Ford chassis units.
