Tonneau cover

Not quite as effective as a full aeroshell, a tonneau cover (pick up truck flat bed cover) can still provide a measurable fuel economy benefit vs. an open bed.

A tonneau is however much easier to install or fabricate.

Perhaps somewhat counter-intuitive, a partial tonneau can be more effective at drag reduction than a full cover.
