So whenever I sleep in my car (Forester) and leave the windows up I always wake up with the windows fogged. Doesn't matter if I sleep alone or with my climbing partner. I usually crack them but after a couple of really cold days in Joshua Tree, I'd like to be able to leave them up. Is there anyway to solve this? I have friends who have vans who don't need to crack the windows (I'm assuming because of the larger volume of a van).
Also, are some great SUV setups for sleeping and storage? Pictures, videos, ideas welcome.
