Hey Wally - when you get time to come to B'Ville - I'll take you to a Sears house downtown...it used to be a B & B but is now a lawyer's office. Pretty Cool. At one time the termites were holding hands holding it up but someone apparently spent some money on it. I have a friend whose ancestors ordered it and it arrived by train and someone put it up! It was big time for us!
Didn't see it move but have stayed in my niece's house. Hers was a two story Victorian, over 100 years old, she moved it from a farm that was being cleared of all buildings, to an acre about five miles away. Didn't have indoor plumbing or electrical service. One bedroom, living room, dining room and kitchen on the first floor. Three bedrooms with steeply pitched ceilings on the second floor. So she turned the down stairs bedroom into a bath, put in plumbing, installed a kitchen sink, built cupboards, installed electrical service and lived there happily for about fifteen years. Her crowning touch was the front porch railing, looked all over for a decoration for the newel post. Finally bolted a croquet ball to the top of the post. Painted it to match the railing. Since freeways have been built fairly recently in the Phoenix area, never was too sure when out in the outlying areas how long a house had been there. Would find 3,000 to 4,000 square foot concrete block homes over fifty years old relocated in some of the strangest places. Some of those concrete block homes that were in the path of the freeway and now located 200 miles away from their original site. And the only clue would be the squares that haven't been painted yet, at the bottom of the concrete block where the I beams had been placed to make the move. And the bottom row of tiles around the shower wouldn't match the rest of the tile. Scattered all over the state are homes that have been moved out of the path of the open pit copper mines. Home I had in Hobbs, NM was two homes that had been transported from a gas line company camp about 100 miles away and put together into one house. Have never lived in a mobile home or a manufactured home but have lived in several homes that were "move ons".
U.S. Homes, a major builder, is effectively a prefab builder. Instead of 2x4s, etc, trucks roll up with completed walls. They assemble them on site, much faster than typical stick built homes, but they are effectively a stick-built home. No market resistance.
