Asphyxiation from sleeping in my Cruiser?
I'm headed out on the Outlaws run and I'm set up to sleep in my Cruiser. It's an 80, so it's pretty spacious on the interior. Assuming I sleep 7 hours a night, does anyone know if I need to crack a window? I'd prefer to keep the warm air inside for sleeping, but I also don't want to run out of oxygen.
