Hi Brian, Just wanted to add something on the subject of a mail order house. There is a tourist attraction near here that is the remains of a Steam Ship that sank many years ago. A local family along with a friend dug this up and created a museum with to ship's cargo on display and photos of them unearthing the Steam Ship. Part of that cargo was at least one complete prefab house. The museum is just called The Steam Ship Arabia. Should you be a follower of the History Chanel on TV you may know of their Oak Island series. The brothers are going to have a new series that follows other treasure hunters' projects, and they are going to do a profile of The Steam Sip Arabia in one of the installments if that would be of interest.
