have you ever slept in your car

Not really sleeping in an A body, so it doesn't really count.

We had no air conditioner in an overcrowded house after Hurricane Katrina. My oldest son and I opted to sleep in our Durango. We had a queen sized blow up mattress and slept well using the air conditioner. I was worried about CO2 buildup, so I only ran it 15 minutes at a time. It seemed to stay comfortable for a little over an hour, but man it sure felt good.
