Would airflow reattach after the short step down from the roof?
How much better would it be than a flat tonneau?

My neighbor Bob did it to his Chevy 1/2-ton and for good effect.Doped fabric over EMT frame.Very light.Bob has gone to the big airfield in the sky now so I can't ask him to remember and share the results.I just remember his grin from the 1st tankful.
