Using a small low energy fan would be a good way to help distribute the heat quietly and efficiently.
Yes. This is exactly what I saw in one trailer. A small fan hanging a few feet over the wall-mounted cat heater. Not an exhaust fan (his heater doesn't have any), but a fan to help spread the heat because cat heaters are very directional. In my planned mount the heater will be aimed right where I need it, so fan hopefully won't be necessary.
CO sensors work, yes. Cheap ones simply trip off when certain threshold has been exceeded. Expensive ones also provide digital readout of the current CO content and a few previous days peak readings. What they DON'T do, is removing CO from your air. There is enough CO, CO2 and other fumes in my urban life, and if I can improve air quality in my trailer by forceful venting, then I'm going to do this.
