Air8 Window Open or All Closed?

Open the roof vent a bit (do not turn fan on), put one window at the one click barely open. This provides a convection type of circulation, similar to your return air vent at home on your furnace.

Elwell and nuCamp also recommend a small fan (a good quality 8" USB desktop fan) be used to circulate the air. I typically leave the galley window in "vent" position and crack the roof vent a bit, as @Verna mentioned. 

@AirBoss, my advice above is as a user of 4 teardrops. It works for me. I pretty much keep the 10+ speed Fantastic Fan vent open all the time, without the fan on. If the dogs need extra air, I do have a USB clamp-on fan that I can easily point at them.

Verna, understand completely. Just passing along the advice from the Elwell folks themselves.

Denny,
Yes, the Air8 has a fairly large intake under the trailer, directly below the unit. To the best of my knowledge (and that's not as a SME by any stretch!), these units do not have the "recirculate" button as on an auto. The only air it uses to cool is ambient outside air. As we know, the recirculated air in the auto cools faster and is more effifcient for the a/c unit as it's not having to work as hard to cool 90 degree outside air...the air it has to cool is already at 75 degrees or so and droping.  

If I learn more about all this, I'll pass it along.

First mistake I made since lunch! 

At least no one got hurt.

On Page 24 of the Nucamp 2019 edition T@B 400 owner’s manual, it says to close all doors and windows when running the Coolcat.  The Air8 manual is quite sparse, and mentions nothing about doors/windows.

I'm headed out early in the AM for 8 days. Temps in the hi 80's low 90's expected in northern Sierra Nevada's. 

I'll report back. 

Where are you going? I was up at Plumas National Forest last weekend.
