Hi. Most of our Airstreams have stoves and ovens. Mine has an over the stove hood with a vent fan to exhaust cooking odors. I am not aware of any special venting necessary for a stove. Don't use it to heat with, use it to cook with only. Our furnaces, water heaters and fridges all have special combustion venting requirements.
Your Atwood installation instructions will give you specific requirements for the propane hook up, the cabinet size, and clearance around the stove. Follow these instructions and you'll be fine.
