This is just a quick update, but I am happy to say that I finally have a plan to load the house on the trailer and move it! I picked up about 300 pounds of square steel tube and C-channel from the steel yard today to start preparing the trailer. I am going to bolt the tube along the bottom of the frame of the house to act as skids. The C-channel will be welded across the trailer to bring the width out to 8 feet. Each cross beam will have another piece of the C-channel welded on top to act as a guide. When the time comes to do the move, I will line the trailer up with the house, hook up a winch and pull it up steel ramps, into the guides and onto the trailer. Picture one of those trucks that pick up dumpsters: it is a very similar design.
My goal is to prepare the trailer and move the house by the end of next week. I will put out a call for help when I know what day I am moving. Wish me luck!
