I still wonder what kind of attack we want to prevent here.
If it is gas (anesthetic, etc.), then if it's not possible through the window, it will through the fridge or kitchen hood vents or some other opening...
Hiya
You may be aware of this advice from other sources, but I'll post it anyway!
There are quite often stories in the UK press regarding supposed gas attacks on campervans on mainland Europe, with valuables being robbed during the night, no one woke up during the attack and all occupants have headaches in the morning. Police are always called but nothing ever seems to be found.
This possibility concerns many, and in response to this concern the Royal College of Anaesthetists made a statement dated 13Sep2007;
"Despite the increasing numbers of reports of people being gassed in motor-homes or commercial trucks in France, and the warning put out by the Foreign Office for travellers to be aware of this danger, this College remains of the view that this is a myth.
It is the view of the College that it would not be possible to render someone unconscious by blowing ether, chloroform or any of the currently used volatile anaesthetic agents, through the window of a motor-home without their knowledge, even if they were sleeping at the time. Ether is an extremely pungent agent and a relatively weak anaesthetic by modern standards and has a very irritant affect on the air passages, causing coughing and sometimes vomiting. It takes some time to reach unconsciousness, even if given by direct application to the face on a cloth, and the concentration needed by some sort of spray administered directly into a room would be enormous. The smell hangs around for days and would be obvious to anyone the next day. Even the more powerful modern volatile agents would need to be delivered in tankerloads of carrier gas or by a large compressor. Potential agents, such as the one used by the Russians in the Moscow siege are few in number and difficult to obtain. Moreover, these drugs would be too expensive for the average thief to use.
The other important point to remember is that general anaesthetics are potentially very dangerous, which is why they are only administered in the UK by doctors who have undergone many years of postgraduate training in the subject and who remain with the unconscious patient throughout the anaesthetic. Unsupervised patients are likely to die from obstruction of the airway by their tongues falling back. In the Moscow seige approximately 20% of the people died, many probably from airway obstruction directly related to the agent used.
If there was a totally safe, odourless, potent, cheap anaesthetic agent available to thieves for this purpose it is likely the medical profession would know about it and be investigating its use in anaesthetic practice.

From http://www.rcoa.ac.uk/patients-and-relatives/common-concerns-and-faqs Link and page had been changed since I 1st posted
In my opinion this is a minority of people alleging they have been attacked in this way to claim for missing valuables on their insurance. The stories always make headlines, yet I have yet to read of any evidence found to prove what had happened. From the RCoA statement above you would think it would be obvious from the smell at least.
Don't worry about it!!
