C3H8 (propane) + 5 O2 (oxygen) = 3 CO2 (carbon dioxide) + 4 H2O (water)
when you start to run short on O2...
C3H8 (propane) + 4 O2 (oxygen) = 1 CO2 (carbon dioxide) + 2 CO (carbon monoxide) + 4 H2O (water)
thus: oxygen consumption = CO emission
Relying on its low O2 sensor to prevent carbon monoxide poisoning is putting all your eggs in one basket.
This brings up another interesting science fact. For every # of propane burned, you release ~1.6# of water into the air. The Mr Buddy uses those 1# bottles. I've seen them go through one a night if not insulated well. Thats 3/4L of water in the air (excuse me for going over into metric to make calculations easier.) IIRC, a human sleeping exhales about 1/4L/night. So that like having 3 more people in the trailer w/ you. FWIW, my family of 3 sleeping in the van generates noticeable condensation inside overnight. Not dripping, but a noticeable 'film' on everything.
The heater consumes enough oxygen to trigger low oxygen long before it produces enough carbon monoxide to be unsafe. Even if the oxygen sensor didn't work and the heater kept running, the environment would have low enough oxygen to not only kill you but also stop combustion. Due to how efficient the catalytic heater is, the carbon monoxide emission is still so low it isn't a concern. A low oxygen environment is immediately deadly.
Like I said, it's a good idea to keep a window cracked. It's not because of CO emissions, it's because of oxygen consumption. When I run mine, I keep the roof vent open and a window cracked.
The real solution is a furnace that does all of the combustion outside of the living space or an electric heater. Both of those options are safer and don't put moisture in the sleeping quarters.
Brent, I installed strips of L-Track on the bed rails of my truck. It's as versatile as E-track, but much smaller. I forget what each connection point is rated for, but it well exceeds the load a dirt bike would put on it.
