I had been driving for about an hour returning from a camping trip when my wife and I noticed a burning smell in the cab of the vehicle. About 5 seconds later smoke began filling the interior. I pulled over and got my family out of the vehicle, which includes my wife, two kids and a dog. I went to the front of the vehicle and saw flames on the passenger side inner fender as well as the top of the passenger fender. With the help of a friend who was traveling with us, I was able to extinguish the fire with a fire extinguisher I always carry. I think its safe to say a vehicle fire put my entire families safety at risk. I have contacted my insurance company and filed a claim, however no inspections have been performed yet. There were no warning lamps indicating there was an issue.
