Ventilating Covered Pickup Bed?

Because I plan to carry a generator and gasoline can, I plan to trade my van in for a pickup this fall. Since I want to secure things in the bed I will be installing a tri-fold cover. I know that the bed moves enough air that it's probably not a safety issue, but I would like to have some kind of ventilation through the bed while traveling down the road. Has anyone made a modification to accomplish this, especially something stealthy? No guesses please - just facts!

You may want to install a passive ventilation system using marine type vents. You would just need to drill a few holes in the cover.

They are designed to ventilate gas fumes from the bilge areas of boats, and they do the job well.

Here is a link showing all styles, Vents

Hope this helps.
