What is the best way to pack a unit?

Larger and more infrequently used items should go in the back of the unit. Remember to keep a walkway in the center of your unit to more easily access items. Always keep items labeled and a list of items stored, even a photo on the outside of each box will allow you to "see" what's inside.
