Tips for Choosing the Right Storage Unit
Start by listing everything you plan to store and grouping items by size. Consider whether items need to be accessed over time and whether you will add more belongings in the future. When in doubt, many customers choose to size up slightly to avoid stacking items too tightly. Leaving space for a clear walkway inside the unit can also make your storage experience much easier.
