I have a 12v fan, which is also good to drown out noise as it's loud and blows a LOT of air around.

I'll think about the rain guards, I was just hoping someone had a workaround. I really didn't want to modify my vehicle either permanently or obviously.
(I *do* want to do that with a van, just not with my little hybrid. But if I'm gonna keep it for 200,000 miles+, who cares about resale anyway?)

These look SUPER easy to make, but obviously are not inconspicuous or safe. Still kudos to the guy for the simple design.

I've been lucky in the past (with traveling/sleeping weather) but now I'm planning to travel and car sleep a lot more.
Previously I've camped in vans and SUV's for 3-4 nights a year, but now I have a hybrid hatchback that is sleep-able with a platform...and I have the time and money to drive it around the country.

What can we do to achieve decent ventilation (reduce condensation, or allow heat to escape in summer*) without adding rain guards (window deflectors)? I don't want to add those things if I don't have to.

I'm envisioning being at a rest stop or parking lot and trying to be innocuous--and safe.
At a campsite, I can always just use a tarp.

My current plan is to crack the windows a sliver. Just enough to slip paper through, but barring torrential rain [which would wake me up, anyway] nothing should get in.
Maybe that's enough?

Obviously to the extent possible, I will open the climate control vents.

* Summer heat is its own animal...I assume I'll be up around dawn when its hot, so I'm not talking about day sleeping.

For day sleeping I'd try to come up with a screen solution...but that isn't safe for urban camping.
Or not safe enough for me to sleep well.
