A call to all those who follow storage pods
Each time you think you have fully packed the storage pod, try to move the boxes. If they shift at all, work in more padding. Larger moving storage containers are often provided with eyehooks to allow you to rope your possessions down instead. Use the arrangement of the eyehooks in the storage pod as a guide to mentally section off the pod, then fill in one section at a time completely. Rope it down, then move on to the next section.
