It would be great if you can have "Storage Location" as a drop down item (similar to Categories), that the admin could list where that piece of equipment is stored (a lot of times with large amounts of equipment there are stored in various locations, or various parts of a warehouse).

The locations would have an "Add Storage Location" similar to "Add Category" in the admin backend.

The Client/Customer would not see the location information - it would only be available to the admins.
