I'll be more worried about WATER, sun glasses, canned goods, a good jeep, a gun and a reserve of bullets. A man ? Only he knows how to repair the jeep in need or use that damn gun.*

No need for Water, you're on an island. There's rain, fresh water for the plants, and at worse it's quite easy to make fresh water from salt water (enough for drink and food at least).
