After reading the woodstove article and suffering being trapped indoors by cold, I have the bug to convert a cheapish shelter to a woodstove-warmed retreat. Anybody have a floorless shelter they would be willing to part with. If I am gonna drop $300-400 on a titanium stove, I can't afford a premade $800 shelter, so I was thinking of adding a stove jack to a used 3-4 person, lightweight model. Any condition/brand open for consideration. I'm pretty handy with the sewing machine so a few holes and necessary mods are not a huge concern. Trekking pole support preferred.
