Without knowing more than I do,I'd recommend closed doors.
One of our members in Europe tested his streamlined Nissan pickup,with open and close rear bulkheads and reported better effect with the closed off configuration.
A neighbor which ran a boat tail/ box-cavity on his VW Vanagon saw only limited benefit with the open rear although he was delighted to have extra storage for very light camping gear.
