The fire was fairly fast.
Initial look from inspections seems the failed shaft drove the fuel like and that was why it accelerated so fast.
I had an extinguisher and that's how I saved the cab and kept it under control. If I had kids to get out I probably would have struggled.
I've asked around a lot and between all convos I've had, what I've seen here, etc the actual fire is not typical of the failure but it's a possibility for others. It's not known currently if there was another factor or if it was just luck of the draw that debris or slag melted the fuel line by sheer chance.
IMO fire extinguishers should be in every car, especially if you have kids who may not be able to quickly leave the vehicle. It's worth the money, and a good mount to remove it helps when you're panicking.
I had jeans so I wasn't burned in my legs when I was struggling to reach that extinguisher over all my travel luggage. I usually recommend mounting on doors/seats. When I put the roof molle rack in my cargo area I thought above the rear seats was better but didn't think of when the cab was fully loaded like this road trip.
