Hi Roadcam,
Yes, Mitch is right. The exhaust gasses will come into the van through the open rear windows because of the low pressure area being generated when driving the van down the road.
When my dad first purchased our 69 Club Wagon, he opened up the rear windows and tried to asphyxiate use driving down the road. The comment was, "Dad my eyes are watering and I can't breath. Can I close the window?"
