Just my 2 cents here...... a fire is not to be taken lightly, as in do not hesitate to GET OUT. Fire will spread quicker that you would ever think possible, even in your home, an RV will accelerate that so there is really no time to do anything else but get out. My RV has the foam panels in the walls, they will produce deadly fumes that in only a few breaths will render you unconscious. Its not the fire that kills you, its the smoke and fumes that kills you. Good advice to replace the poor excuse of a fire extinguisher that comes with the trailer with real ones placed in accessible spots so you can actually get to it if needed. People with the bunk house style campers, make sure your kids know what to do in case its needed.
