Thanks for the inputs and insights, joecaption and nealt. I really don' know much of anything about house construction (especially mobile homes), but can do mostly any in-house repairs (drywall, pluming, electrical, etc). I have not seen the house yet, these are pics sent to me; I mention fiberglass cloth because it kind of resembles fiberglass cloth (the type used for auto repair).
That external exposed wall seems to be a bigger concern, it is too bad since it is an almost new house. In the past I lived in a country whereon mostly any house is built out of concrete blocks, mortar, and/or bricks; wood structures and frames seem too susceptible to problems.
