Really, vented designs like proper parking heaters are the way to go, and not just to reduce CO risks.
Fair enough.
Just FWIW, I have used the Coleman Catalytic heaters indoors since the 1970s. Always, always always light them OUTDOORS as it WILL produce an open flame as it heats up and starts catalyzing, once the catalytic reaction starts, CO is so low as to be non detectible by most CO2 detectors.
Nothing in life is without risk mind you. We all know we should drink plenty of water, but it is also true that water to excess will kill you. Common sense should be more common...
Keep the heater far enough away from anything flamable due to the heat produced, provide ample fresh air, Coleman recommends 3 sq in, which isn't much at all. The OPs camper could easily make this by simply cracking, maybe 1/2" open one of the slider windows.
I would be MUCH more concerned about cooking in the camper. Again use common sense, and steer clear of bear country if you are keeping food / cooking inside.
And I just corrected myself. I had written CO2 (Carbon Dioxide) when I meant CO (Carbon Monoxide). I haven't had coffee yet...
And since the subject was brought up, in camping and vehicular environments, CO can come from a variety of sources, even if you aren't heating in the camper it is best to have a CO detector installed and working in the camper. Multiple sources say proper location is 5ft off the ground.
Another issue is if you have a propane in the camper. Propane is heavier than air, and quite flamable. A working propane detector should be installed close to the ground.
