I have a full tonneau that opens up into a ladder rack. I want a take down aero cover to sit on top when I don't need my bed. Might have to go around 14° with my cover as I want my longest piece to be able to fit inside my bed. In ladder rack form its horribly unaerodynamic but I kinda need my truck to be a truck occasionally.
