This is a very serious issue. In an emergency common sense can be lost due to anxiety, fear, etc. The best weapon is preparing in advance. Families should talk about what they would do in case of fire or other emergency in their RV. Beginning of every season would be a good time. The absolute number one priority is getting everyone out, preferably through the door they entered. It is quicker and easier and more familiar than emergency exits. Once everyone is out an extinguishment attempt can be made while one member of party calls for help and alerts occupants of any neighboring RV's. Just like in your home, no one should go back in once they're out.
