Ok don't listen to the last guy. I have a propane 4 burner stove in my house and we are fine. So propane is a clean burning fuel but its not recommended to burn in like that in a home. If you are concerned then just use it by a window. Once again last guy is stupid. You wont suffocate.
I lived mist my life putside in the country using propane to cook and heat. Open vent or window. If you keep your trailer airtight, the walls and windows sweat and next is mold. 30 some years living luke that and I am still here and healthy. I've used 'Mr. Heater' indoors also, I m still here, and can breath just fine
Vent gases build-up you'll suffocate.
