In the 70s, our neighbor had a F**d pickup that his hired hand drove, and it had the in-the-cab gas tank.
The hand's wife took it shopping, rolled it somehow, and the resulting fire killed her little girl. I don't know if the wreck would have killed her anyway.
One can't protect against every possible hazard, but this incident is certainly in my mind when I consider where to put the gas tank in the truck we're restoring for my 17-year-old daughter.
