What do you think could be the smallest size firebox and chimney and still be effective? Maybe a lighter and packable unit? 2"- 3" Dia.chimney and a fire box 4" in diameter. I like the idea of having a woodburning stove. Too bad you can't just have a fireplace inside the tent but Poofffffffffffffff. <img src="/forums/images/graemlins/crazy.gif" alt="" />
