I wasn't saying not to use one. Check my previous post for my installation -- which we use often.
I don't want to make a recommendation on a cat heater without some caution.
BTW, they do emit some CO. See http://www.cpsc.gov/library/foia/foia05/os/co03.pdf

Cats do not emit CO nor do they emit smoke. They are clean burning, quiet, and way more efficient then forced air systems.
The heat they provide is more of a radiant heat which feels much more like wood heat compared to the forced air furnace.
Being a propane device, as with using all other propane devices in your Airstream, you should always have a working propane detector installed (in fact, I think propane alarms are required by law for all propane enabled RVs).
If you check out the link to my install in the '66 you can see the propane detector next to the floor just under the cat install (propane is heavier than oxygen, so if there is a propane leak it will first be detected next to the floor).
