Sleeper vent optimization

We used to have cab vents too. Ahead of the clutch pedal.

Buy the finest copper screen material you can find, cut with sissors and paste over your interior vent screen so that the really little annoying no see ums dont get inside with you.

One trip to a slaughterhouse in the dead of summer with mounds of flies covering rail cars will teach you to keep your vents shut fast.

However.

Left vent is open to incoming air for driving forward. Right vent is open to rear. And so the air crosses the cab to that corner and out. If you have a upper bunk window that is openable and screened you can open the upper right as well. So that if you had to, crack your drivers window a half inch to get a blast of fresh air into that cab blowing out the right side. -50 air is not always welcome. But fresh air is good.

If they still built the vents the same old way that I remember, purchase a couple of 6 inch bamboo sticks 3/4 inch or so. Cross one inside the vertical handle on the inside of your sleeper so that no one outside of you can sneaky pry it open and spray certain chemicals to knock you out cold.

 

I've always like to keep my cabs sealed up, a/c and heat only. If you have openings, all the dust, dirt, pollen, soot, fumes, or what ever is outside your truck; is going to be inside your truck. I know they aren't air tight, but if wants in, I'm not going to make it easy. That's just me though.
