What do you guys mean by manufactured homes. Are we talking about double wides that are basically two moble homes driven to a site and bolted together - maybe placed on a crawl space foundation or just piered and skirted like any other moble home, or are we talking about multi-sectioned houses trucked in and assembled on a foundation or basement. Both of these have pretty much the full interiors done at the factory and have fully clad exteriors. The "manufactured" homes I am seeing alot of here in western PA are factory made wall, floor and roofing sections that are trucked in and then put together via cranes on site-built basements. The exterior work (vynl or brick or a mixture) is mostly done on site as is most of the non-framing related interior, including drywall, plumbing, electrical, HVAC and cabinetry. Virtually all finish carpentry is done on site. I guess the framing and sheathing is what is factory done.
