Mobile storage, also known as mobile self-storage or portable storage, is a super-easy alternative to traditional self-storage. No renting a big truck, scheduling a specific day and time to pack, and then driving through traffic in an unfamiliar vehicle to an unfamiliar location and then unloading. While the containers come in various sizes and store the same amount or more than a unit at a self-storage facility, the containers are brought to you and picked up on your schedule.
