I run a hose in from a bulk tank outside the driver's door in through the
vent window to my Buddy heater. I let the partially open vent window
provide the ventilation.

I also keep a battery-operated CO detector in the van with me anytime I
have the heater running, just to make sure that I'll get a loud warning if
my drowsiness *is* CO related.
