Do you have other useful things you take camping?

My favourite multi-purpose small plastic box!

I carry firewood  in it and empty the wood on arrival at camping.  I then use it as a coffee table for the rest of the weekend.  At dinner time, I use it as a stable table and eat off it.  I later take it to bed with me and use it as a bedside table.  It makes it so easy to find all my bits and pieces in the dark if I need.  Occasionally I watch a movie on my laptop and it is fabulous place to place the laptop.  It also stops ground moisture reaching things, especially the laptop.  I then pack all my rubbish in it and take it home with me.
