I was wondering how many guys carry a fire extinguisher in their truck. I started carrying one a few months ago after my brother in law's classic chevy had an electrical fire and it caused some major damage. Luckily, some guy pulled over and put it out with an extinguisher so the car did not burn to the ground. I carry an auto/marine extinguisher. I hope that I will never need it for my vehicle, but it would be good to have on board in the case that I could help someone else.
