I can say without any worry of being proved wrong that it is very easy to warm that tent to 80+ degrees with even a small campfire like the one seen in the video with my grandson bouncing around inside it.
I use a layer of thicker branches about 3" in diameter first, then I use smaller diameter sticks in layers on top of that. When you light that off the smaller sticks burn down and create a bed of coals on the first layer that keep fuel burning as it's added.
By design that burns low and slow. I'm also burning deadfall from hardwoods, Oak and Hickory by choice, and because that's what's growing in our forest here.
One of the videos has a kid read off a thermometer at 79 degrees (with snow on the ground). You can judge for yourself the size of the fire in that video.
If you can't build and manage a campfire that will not ignite that tent you really shouldn't ever build a campfire anywhere because all campfires are flammable.
>They get warm, but what doesn't when you have a long fire in front of you.
The shitty fireplace in my piss poor excuse of an 80s designed house. It's almost as if it was included as a check mark in a real estate listing rather than how to make it useful.
Yes. And a hole-in-the-wall fireplace will reliably cause a house to get colder in the winter, by sucking warm interior air up and out the chimney, to be replaced with cold outside air drafted in through leaks in the envelope and HVAC penetrations.

Oh, I have plenty of those too! Luckily, in my neck of the woods, winters are more of rare occurrence. We typically only have extra summer followed by late fall before spring arrives.
It's quite possible the author and I have different ideas of what a small backpacking fire looks like.
