Luckily I was parked at a gas station when we noticed the smoke...I thought the truck was overheating. I took out my key and the engine was still making noises. I started smelling something but did not panic thinking it was just overheating. My boyfriend open the hood and that when the smoke got worse. I called my insurance company and they told me to get out to the truck...I did and looking under the truck, I saw flames....
