Nice work on the boxes Dave. Are you going to cut the top of the entryway to the cabin back now that you are going that route? I was thinking of doing that to mine but opted for the less work/original configuration route instead. Great lakes Skippers has some pre made cabin entry doors that looked like they would have worked. making fast progress keep posting.
