    Most people do not understand how CO poisoning works. It is not an easily recovered from thing and here is why.

    Hemoglobin circulates in your blood and goes thru your lungs. On the way back from the body and into the lungs it carries the CO2 it picked up from your body (as a waste product) and dumps it in your lungs (that is what you exhale). As soon as it dumps the CO2 it picks up an Oxygen Molecule and takes that into the body as fuel, dumping it and picking up anothe CO2 ( carbon DI oxide).

    IF there is CO (carbon MON oxide) present in the lung and it picks up the CO INSTEAD of O2 (oxygen) that molecule becomes permanently bonded to the hemoglobin. It cannot pick or deliver any more CO2 or O2 so it is out of comission. For an animal to suffer CO poisoning, they need a pretty good load and they will show other symptoms such as red skin, inability to catch breath, lethargy and coma.

    Modern Cars have a catalytic converter. The CC chemically alters the CO from the engine exhaust into CO2 and water vapor which is then exhausted out the tail pipe.

    If your car has a working Catalytic converter and the Check Engine light is not on, there should not be any CO issues. Even a 1994 car had a Catalytic converter.. and if it plugs you will know it as the car will not be able to get out of its own way.

    This is not to say you should not have the air in the cab of the truck tested.. just saying it is not so likely as you would think unless something is malfunctioning and this is something you would probably know (check engine light or crappy running).

    Sounds like a deep sleep to me, if it's only in the truck it's likely when asleep she doesn't feel shaking as anything more than what the truck does normally, sleeping in a car requires sleeping through bumps and shakes.

    I have had dogs wake up as the OP describes on occasion, but never had one that did it predictably. Usually only after getting really really worn out.

    I'm personally favoring the deep sleep theory at the moment, although I am going to get the CO levels tested. It would be a good thing to know and I -- hobby mechanic -- have swapped engines and exhaust systems on the vehicle so it could certainly be possible.

    I just think that if levels were so high that she passed out within 1/2 hour of driving and was unable to respond to me touching, shaking her, etc. (1) I would have noticed something when I drive with windows up, and (2) she would not have woken up and sniffed around and happily gobbled down a pig's ear when I turned the truck off.

    An easy check would be to take her for a drive in another vehicle and see if she does it.

    ^She doesn't, or hasn't yet, but I'm not sure that shows very much. Of the hundreds of times we have driven in the truck (many times w/ windows up), this has only happened once (twice if you count the less dramatic version when she was much younger).
