And in keeping with the escape emphasis....everyone should make sure they know exactly how to use the fire exit windows. I am willing to bet that a great deal of RV'ers have never even tried to open the fire exit windows. Know how they work, and release them a time or two a year as they have a tendency to stick to the trailer frame, but a simple push usually gets them to release. There is a very good chance that if you do have a fire, unless its in the day when you are sitting in there, going out the door may not be an option.
As Silverback has said, if they catch fire, they are like a matchstick, and time will be of the essence, most importantly at night when you are sleeping. Believe what I say, 25 plus years as a career firefighter...know your escape route!
