Heh heh, our website does get a bit overwhelming sometimes. You need to go to the options page. Here is the link http://tinycamper.com/options6.htm . Click on "Air cond" .
This will show you what the air conditioner looks like and what the external vent is. We have a cover panel the exits just above the hatch hinge. It is really a three part vent with two input air intakes and one output. The whole thing does not stick above the roof line so is really only visible from the rear.
