hello i have an old propane heater.  i might try to put into my tiny teardrop.   its vented to outside. it has no fan and no battery power is needed.  i wonder if a propane heater for instance the wave 3 will work better for me in 2020.   it says for the wave 3 just crack a window.  so does the wave 3 have nasty fumes or not.  i want dependable heat safe , and not a loud fan that operates with it.
