This is just to give you an idea of what the layout might be like.   Feel free to use your imagination.

"When groups are traveling together the wagons are often arranged in a circle, end to end, tongues inward, narrowing gaps between the "sections" of the improvised rampart, and chained together, the front axle of one wagon chained to the rear axle of the next, the camp, and the draft animals, and any accompanying livestock, within the circle. Often this circle can be quite large, with the circle being five wagons deep. This, however, is not the way of the wagon peoples of the southern hemispheres due to the large number of wagons. There the wagons congregate almost to form wagon cities." — Renegades of Gor, page 7.
