It can be more practical to have a mobile home in some places --- areas that flood for example --- here in the areas that have flooding, those up higher in their mobile homes don't have to scrape 2 feet of mud out of their homes.
True. I was in one during a flash flood that had water almost up to the floor. I never realized how fast water could rise before. One minute, just the grass covered and 15 minutes later it was two feet deep.
