So as I planned how to build one in minature, I first decided I would need to build an awning over the desk area (in case it rains). Then had to decide what was going on inside the wagon?
Obviously, if I were a general, I'd have a place to ride and do some work, so a small desk and chair at the front of the wagon in a wood paneled office. And why not a proper bed in the back of the wagon?
Of course I would have a portrait of my dear wife and maybe some nice wall paper on the wall?
So some quick Google searches for images and a quick visit to Photoshop.
Lots of work to do yet. Needs bedding and curtains (like the ambulance) A couple of chairs--I have some of the Old Glory seated officers on chairs. An awning over the external desk. And how to build all those little mail slots on the outer office?
