I have read other websites that this is freestanding, but here it says differently. Can anyone say for sure if it is freestanding or not?
The tent itself is freestanding, but the convertible portion needs to be staked out with at least two stakes for the vestibule.
You should always secure (stakes or alternative) if you want your tent to be there when you return to camp. it is, however, freestanding with the noted vestibule portion requiring stakes.
