Make a List
Not everyone has a perfect memory! Keep a list of all items in the storage unit so you always know exactly what is in all of those boxes.
Raise it Up
Prepare your unit by placing pallets, blocks of wood or cardboard on the floor under your items to minimize the possibility of water or moisture damage. Avoid using plastic as this can cause condensation to accumulate.
Provide Easy Access
Consider whether or not you will need access to any of your items while they are in storage. Try to place those items near the front of the storage unit, and if possible, leave a walkway opening into the unit.
Label your boxes and arrange them in such a way that they can be easily read.
Place heaviest boxes on the bottom when stacking, and light, fragile, or otherwise crushable containers at the top.
