Pardon my presupposition.

The tonneau was 50/50 I need something to cover the bed and keep stuff mostly dry during trips. Worst case for long drives without needing the bed I can cab up a half cover for the bed and a custom headache each with a fin for the rear cab spoiler.
It folds in half? Here's a golden oldie:

Camping World Cup trucks use a simple spoiler that follows the 12 rule.

No reason why the spoiler couldn't be clear plastic, and/or retractable. It doesn't need to be a rectangle, a half-octagon or curved arc would have less frontal area, and conform to the vortexes that stream off the back of the cab.
Walk without rhythm and it won't attract the worm. --fatboy slim
