Hey Chris, I know you were wondering about the quality and strength of modular (pre-fab) homes. Check this out from Kiplinger's...
"In assessing damage to residential neighborhoods in Dade County, Fla., after 1992's Category 5 Hurricane Andrew, the Federal Emergency Management Agency reported "relatively minimal structural damage in modular housing developments. The module-to-module combination of the units appears to have provided an inherently rigid system that performed much better than conventional residential framing." Translation: Prefabs can hold up better in extreme weather conditions than traditional stick-built structures."
