Roof rack for four days

air flow
over the roof off the windshield… can flow over the bows if bows are moved BACK on the roof, if possible.



Not into the bows causing drag and worser airflow thru the hulls, thru the rack ! aaaiiiieeee…



even with an E250 5.4 SOHC, a foot or 2 more BACK is abt mph on the Interstate.
