In front of the house is a massive ash tree. Tank, like the rest of the Oberlin cooperatives, is entirely student-run with all participating students working as cooks, buyers, administrators, and coordinators. Most decisions within Tank are made by modified consensus. Similar to Keep and Old Barrows, Tank has a tradition of meat-friendly meals while always having vegetarian and vegan options. Due in large part to its spacious lobby, wrap-around porch, expansive lawn and communal swings, Tank has long been a social anchor of the East Oberlin student community. In the cooperative spirit, each member of the house has an assigned, equitable task requiring some five hours of cooking or house maintenance every week. The Oberlin Student Cooperative Association (OSCA) remains a nonprofit organization, and refunds unspent room and board to its members at the end of the school year.
