Not sure about the baffles, but I can tell you that I camped in my Bambi a few times over the winter and found no cold air or otherwise coming from my 11k BTU penguin unit.
Which unit do you have the 11k, 13k or larger BTU A/C?
BTW, seeing that you are in Wheaton, check out the Midwest meet. I'm not too far from you and will be going in June. It would be great if you could make it. You could see and talk all kinds of Airstream shop with us all! Anyway here is the link:
