When you park the Vanagon during the summer months it can get hot quickly. A 12 volt oscillating fan can be helpful to move the air around. I like to clip mine on the rear view mirror, or the ash tray lid. The dash board seems to be a favorite location for a fan, but people have different ideas for the perfect fan placement. Where do you mount your fan?
