So I built my survival shelter and I decide a nice fire would really warm things up. Is there a way I can build a fire that would heat the shelter without too much smoke? I know I could make the shelter better and warmer, and I would need to sit and stare at the fire making sure it didn't burn the shelter down.
Is there a way to build a fire to do this? Side note, I am assuming a typical low crawl in shelter, would there be a better one to use with fire?
