An improved bulkhead and partition system in which at least two panels are independently attached to mounting members such that each panel can be moved independently. In a preferred embodiment, two bulkheads or panels are slidably attached to separate pairs of ceiling-mounted rails in a refrigerated trailer such that each bulkhead or panel can be independently slid toward the front of a trailer or toward the rear of a trailer to define, in cooperation with a removable center partition wall, a plurality of different cargo areas to be maintained at different temperatures. Alternatively, two bulkheads or panels may advantageously operate without a partition wall such that the panels may be placed side-by-side and fastened together to make a full-width bulkhead.
