You need at least one thick-walled cooler with foam ice in your Hurricane inventory list as it will save you a lot of money from a tax point of view while being lighter in weight from a convenience point of view and needing to be careful about reliability with your stuff it doesn't take much longer than that.

There is a responsible option for storing temperature-sensitive items (ice, water, food, drink, medicine, etc) that won't break your bank and keep your items fresh for days instead of hours, and it would be a walled foam cooler (sometimes mistakenly using an icebox a styrofoam cooler), made of space-age, lightweight, inexpensive expanded polystyrene (EPS).
The well-designed thick-walled coolers are manufactured with superior quality in a manufacturing process to ensure reliability, tightness, and thermal durability. This type of foam cooler is typically at least 1.5 inches thick and has been thoroughly tested for strength and water resistance.
Better insulation properties – Sometimes referred to as a "sandbox", the thermal properties obtained from the melting process of the material can keep food and other items cold and fresh for days without having to be refrigerated first (a problem caused by shell coolers hard start due to their Surface temperature to melt the ice immediately).
Much Easier to Carry – Lightweight makes it easier to work with heavier, hard-cooled coolers. So when they come with consumables that need thermal protection, they don't add to the weight you need to carry if you move or evacuate.
