Winnerwell fastfold titanium stove can be run without the top so you just have a firebox.
That would give you a stove for heating a tent as well if you add the top and the stove pipe, just for a "two birds with one stone" option. Without the top and the stove pipe, as you'd run it as just a fire pit, she's likely very very light, I like the fold design of them as well, but I digress.
However, they do also have more basic firepits and even have grates and grills for them for cooking.
