Again, I'm not really sure ?
Just throwing my 2 cents in there.
I was thinking more of how most truck camper manufacturers, travel trailers, and RV's use propane stoves inside as standard equipment.
I have not seen an RV company offering a butane stove in a truck camper ?
I think the propane stoves we use in the campers and the propane regulator, make it a bit cleaner burning on propane ?
Not sure ?
Yes, you are right. I would never use a portable propane camping stove inside a building.
Butane seems to be better for cooking inside a restaraunt or big open spaces.
But that is usually done in a big open environment with lost of air.
Burning a butane stove in a small camper that is closed up to fresh air, might not be the best idea.
I'm just saying it would be a good idea to allow for some good ventalation when cooking inside a camper with any gas type method.
Better to be a little on the safer side, rather than sorry.
Shoot ... HERR42 almost ran out of oxygen in his camper with 3 big guys just breathing all night

We are talking about PORTABLE stoves; not built in ones. At least that is what OP asked.
And yes; it is just common sense to vent a small enclosed area when cooking.
