I love these!!

There are companies that offer custom-made screens for vehicles, but they're rather expensive. I bought these from Magzo. They are designed for home doors so they're square, but they work fine for my purposes. They ship from overseas so they do take a few weeks to arrive.

They come with adhesive velcro that you attach to the edges of your doorframes, and the edges of the screens have velcro sewn on. The bug screens are magnetic so they snap together easily in the middle. When I want to leave 'the door open' I just stick them to the vehicle.

Bugs are really attracted to the light so they like to hover around, especially at dusk. This does a good job of keeping most of them out so it's nice to be able to leave the slider door open for a nice breeze.

Sometimes if I'm pulling over for a few minutes at a gas station or rest stop just to get some work done or eat dinner, I don't want everyone peering inside my van yet am too lazy to put all the windshield covers on. This is when I pull down the cab curtain. It's also insulated so I put it down on cold nights. The cab area gets slightly colder than the rest of the vehicle, because of all the windows, so I think it makes a difference.

I bought these blackout curtains, had them hemmed down to size at a local drycleaner, and added grommets using this grommet kit. Here's a time lapse video (at left) of the grommet installation. (Not super exciting, I know.)

The van felt like it needed a welcome mat. I do use it to wipe off my feet when entering. The floor still gets pretty dirty but at least it's a small area so it's easy to clean. I keep this tiny dustpan handy too. The mat is 15" x 6.5".

Honestly I was a little disappointed when it arrived because the lettering was a little bit crooked, and the seller never responded to my request to redo it. But it was only $22 (including shipping), so I guess I'll live with it.
