Anyone seen a heater somewhat like this one selling in aus ? If so let me know !

I like the idea of having the flame, gas and carbon dioxide created left outside the camper but I'd like it to be versitile to swap from tent to camper etc depending what we take.

and your typical diesel heater seems like a pain and are bloody expensive.

Or any ideas would be great!
