One point to Hiawatha for the complete answer.

Because this vehicle was mentioned in another puzzle, I figured it should be included.  When I discovered that vehicle #2 had very few pictures online, I decided it should be the subject of my puzzle.

Even two beds and a bathroom for the personnel were included.
