ITs a small gas bbq type stove.
I'm not really bothered about carbon monoxide poisoning. Awning is very cheap and therefore a terrible fit! Even with the doors shut its as breezy as anything but if I did use the stove I would use it with the main door fully open.
It's more of a fire risk im bothered about. I could put the stove well away from the sides and stay with it all the time while I'm using it.
Ive spent 20 years cooking on little trangia type stoves in various tents, in the main part, and managed to never set anything on fire.
But I guess I'm becoming more safety concious as I get older and now thinking maybe I shouldn't have done.
Plus I've just read an account of someone who was using a Cadac plumbed into his caravans external gas point and there was some fault either with the Cadac or with the gas point and there was a massive ball of flame which destroyed his awning and then his caravan. But that must be a million to one chance. And to be honest even if he hadn't been in his awning his stove was 2m away from a big Calor gas bottle so I don't think it would have been a good outcome no matter if he was in the awning or not.
