Not exactly camping, but I'm part of a Viking re-enactment group and we go for long weekends and stay in Viking or Saxon villages. That's wattle and daub huts, with wooden sleeping benches, so quite like camping.
In our local group they say there's the gender you were assigned at birth, the gender you are in the 21st Century, and the gender you are in the 10th Century. In some cases that's three different genders.
