Is the vortex under, as in right behind the tailgate?
I'm curious about something maybe some of you can help with too... my tailgate can open about half-way, basically at about a 50 degree angle, so what would that do for airflow? Would there still be a cushion of air, though less than if the tailgate was all the way up, that sent most of the over-the-truck air to flow fairly well?
