That's pretty neat, all that varnished wood brought back some memories of a Liberty we had in the late 50's/early 60's. My dad was also in construction and there were a lot of big projects back then (dams, factories, atomic plants, highways) that guys would travel to, and the wives wanted something they could call "home".
I could be mistaken but I thought I saw a HJ in one of the old black & white photos.
