I'd assume what happens is the output is H2O at first, but as the oxygen
in the vehicle gets depleted the combustion becomes incomplete and CO
starts to appear.  At very least it seems like a good, loud CO alarm would
be mandatory, but I'd want one of those with *any* heater.

I personally would not want to use any non-vented combustion heater in
such a small space.
