Wow, this is almost a one stop shop for bug out lists. This is one of my favorite discussion topics. I am a firm believer in the kit that you can hump on your back in addition to the kit in the 4WD.

When I have more time, I'll add things I think were missed from my list, but off the top of my head something I would recommend are those trick birthday candles for fire starting. They are cheap, lightweight, and wind resistant. Use your match to light the candle and the candle to light your fire. Pre burn the candles before you pack them to make them easier to light the second time around.
