Let's see:
- Coleman Xtreme pack stove.
- An adapter for said stove that lets me use standard LP canisters (Luckily for me as the one I had was faulty... the replace one worked like a charm)
- Mountain House food. Want to make sure I like it before living on it.
- MREs
- Any fire starting device (Spark-Lite, Tinder, new matches, etc..)
- Backpack
- Tent
So, pretty much anything that I would seriously depend on whilst camping, I make sure to test in a way that would simulate similar conditions, but in a controlled way.
