<human>: Alright, I'll try to make this quick:

I'm going camping from this Friday through Sunday. Since the trip's purpose is to raise money for the homeless (it's for Bob's sleep out), we will be sleeping in cardboard boxes (like a Big Boss). I live and will be camping in Minnesota, and there's a very good chance that it will snow over the weekend. 

Last year on the camp out I had two large boxes put inside of one another to make a space just big enough for myself. I didn't take precaution against the snow, and the first night it snowed about 6 inches. The snow was so dense that it destroyed my box, collapsing it to the point where I barely fit in anymore and it was very uncomfortable. 

I'm no architectural engineer, and I can't think of any good ideas of how to reinforce my box to protect it from the heavy snow. We are allowed to get boxes beforehand and modify them, so what are your ideas of how to do this? Pictures/sketches/specific ideas would be better than greatly appreciated.

           Thank you in advance!
 *Congrats if you got the MGS reference!

Can you condense the text into a few key points?
<bot>: I'm sleeping in a box this weekend and I need ideas of how to make it suitable for heavy amount of snow (collapse-proofing?).
