I wonder if their smoke alarm had batteries in it and was it in working order, I have two smoke alarms in a 17' trailer just to be sure. I check the alarms before every trip. I told my wife that if there is ever a fire, RUN for the exit. The fire extinguisher is next to the door, if you can't put it out with that one extinguisher, leave. Trailers are not cheap but a life is priceless. I can always get another trailer. She also knows how to break the rear window with the baseball bat that is in the rear of the trailer for that exact purpose.
