History Mobile Mini, or Mobile Mini Storage Systems as it was first called, was founded in 1983 by Richard Bunger and started by selling storage containers to construction companies and manufacturers. By 1986, the company expanded into markets outside Phoenix but in the Southwest region. Due to a shortage of cargo storage containers available, Mobile Mini started manufacturing containers in Phoenix. The early 1990s also saw the development of Mobile Mini's patented “bi-cam locking system.” As manufacturing facilities grew to accommodate new product lines and innovations, larger facilities were created, and Mobile Mini started building modular classrooms for the Arizona and New Mexico markets. In addition to these innovations and changes, Mobile Mini experienced huge growth in Texas, including Dallas, Houston, and San Antonio, along with completing acquisitions in 1998, in Las Vegas and Oklahoma City. In the 2000s, Mobile Mini continued to experience phenomenal growth. The next evolution locking system, the patented "Tri-Cam Locking System", provided customers with security in the moving and storage industry. International expansion occurred in 2004 with the acquisition of Royal Wolf in the UK and the subsequent launch of the Mobile Mini UK website, www.mobilemini.co.uk. In 2008, the company experienced a transformational merger with The Mobile Storage Group, giving Mobile Mini a combined portable storage and office rental fleet of more than 274,000 units. In 2013, Mobile Mini appointed Erik Olsson as CEO. In November 2014, Mobile Mini expanded its product line by purchasing Evergreen Tank Solutions for $405 million in cash. ETS was a leader in liquid and specialty containment solutions. With a fleet of tanks, trucks, pumps, and filters, Evergreen was a solid acquisition with a similar business model. In Spring 2015, Mobile Mini announced the decision to divest 9,400 wood mobile offices
