Very cool find for a history buff. Technically a camping rig, yes. But an expedition rig? Well not really.
I'm sure Doug, you've seen these all over in your travels but for the flatlanders and new kids on the block, this is called a Sheep Wagon. These were typically pulled by two oxen with a head yoke or collar, like is visible in the other photo.
The traditional design for this wagon came into use in the 1880's with the rapid expansion of the sheep business throughout the West. Compact, efficient living space with well-designed storage areas, built-in benches, retractable table, wood stove, and a sleeping berth were common to all sheep wagons.
Early in the American west, millions of sheep were grazed on the rangelands. A lone herder and his dogs could tend a couple of thousand sheep. The sheepwagon was the herder's mobile home, pulled by oxen as he followed these herds. During the grazing season, sheep were often moved hundreds of miles. These wagons served as shelter, home and refuge from the elements of the open range. It's a cowboy's castle.
These are still used out west for sheepherder's and monitoring large bands of sheep. New ones are still being manufactured today and old ones have been used by some savvy ranchers as guest quarters on their dude ranches.
Here are typical interior views -
