When you use a White Box Mobile Storage Unit there's no pressure to get the moving truck back on time. You can have a White Box portable storage unit delivered as early as you would like and you can pack and unpack it at your convenience for as long as you need. Skip unloading and reloading at a traditional self-storage unit. We can store your items at our St. George, UT location until you are ready for the White Box Mobile Storage unit to be delivered at the new location.
