Pictures of roadside RV fires are more often than not motorhomes. And when the pictures show the fire shortly after starting, it is usually coming from the engine area.
Don't often see pictures of roadside travel trailer and 5er fires, but those are most likely from the fridge as there is not a lot of other things likely to start a fire.
Latest numbers from NFPA show that there are an average of 287,000 vehicle fires per year! :E
From
National Fire Protection Association website.Almost two-thirds (64%) of the highway vehicle fires began in the engine, running gear, or wheel area.Next time you are on a long trip on a major highway watch for all the large blacken/discolored car size areas along the shoulder of the highway.
