Probably the most common extra-large size is the 10′ x 30′ unit. Some large units come with electricity sockets and plumbing, so are more than just simple storage and could be used for a variety of activities—with the facility owner’s permission.
The most commonly found extra-large unit is the 10′ x 30′, which is the size of a master bedroom. With an 8′ roof, such a space would offer you 2,400 cubic feet, but due the fact that these spaces are often used for specialist purposes, the height may be even higher than that.
This size unit can accommodate the contents of a loaded semi-truck, in other words all the furniture from a large house. Alternatively, they can hold a car or two plus tools and so forth. Boats are quite commonly put into units of this size.
We reckon that a 10′ x 30′ unit could cost you between $150 and $400 monthly, approximately, or from $250 maybe up to $1,000 for one with climate control.
