I have experience hiking - just walking, not ski hiking - while carrying a soviet made aluminium framed backpack. The frame sometimes touched my back as I walked and after 3 or 4 days, that spot was bleeding. Another person had to carry my backpack until we reached a small village where I bought new frameless one.
I also have experience being tasked with keeping a stove on all night by replenishing the firewood. Not in a tent, in a house. I couldn't... I fell asleep before dawn and this wasn't even on an exhausting hiking trip.
And another maybe relevant experience: I've seen soviet military issue canvas tents. Probably a newer version than what the Dyatlov group had. They were completely useless. Good in the summer to dine under, it does block out the sun. But they are not properly waterproof which baffled me. Rain would leak in along the seams, and in some places the coating was so poor that water would just seep through the fabric. Some others in our group had US military issue tents. The difference is day and night. Not a single drop of water inside, whereas our stuff got completely soaked after one rainy night.
