The early version of a tent camper. I saw a guy a few years back with a team headed down the road. I think there is still an adventure company that uses them.
No they use OX If you know about History Independence, Mo just east of Kansas City was the head of the Santa Fe, Oregon, California trails. There was some people following the trail the old fashioned way.
Saw a truck camper on a trailer once
.They had taken the grunt window out that would match up with the truck back window and was driving a team of mules through the window. They were on a cross country trip. They were in middle tn headed east.
