Old topic revisited.......
Our DIY screen ended up being permanent. Obviously it works great keeping bugs out.
The biggest issues are: the person in the passenger can't take photos with the screen in the way and it can make it harder to see the view in the mirror on that side in some lighting conditions.
We'll keep it to use when setup long enough in one place but will try another approach for bug free and secure ventilation in the cab area. I saw this 3.5"x5"x6" x 4' piece of gutter filler in Home Depot.

The idea is to carve it down to an approx 2" sq x 3 ft long strip to use as a screen filler where the side windows meet the door frame. It will be hidden by the Ventvisors.
We've found that you can just about eliminate condensation on the inside of the windshield if you make sure to have some ventilation up front.
Storage and use of these strips may prove to be a hassle so I'll post again about them once done and I get a chance to use them.
