Bad Day in West Texas

Is that a older Ford? From maybe the 80's -90's ? In that era the Fords had bad ignition switches and a bad plug on the back on the alternator. Both of which have been known to start a fire. I always changed out my ignition switches for a replacement and better switch right away and cut off and replaced the plug on the alternators myself.

Notice that it appears to be thoroughly burned out in the engine compartment. I wonder if that's where it started. The front of the RV is trashed more than the rear. If it started in the house I would expect the rear to burn down well before the engine compartment got involved.

Heartbreaking...hope everyone's okay.

I have quick disconnects on all my batteries but still not sure I could get to them in time if the problem was electrical.

Many times when a vehicle starts on fire it is an electrical fire.
When a wire shorts out if a fuse doesn't blow the wire melts and fire occurs all along wire,many times this is in a harnass or under dash,etc .You have to unhook batteries before they can be even tried to be put out,most of the time by this time you cannot put them out.

I know once fires get going they go fast. But, it looks like he was driving down the road. I wonder why he couldn't put the fire out? But, I've never had a vehicle on fire so I have no idea of how fast it spreads or anything.

Feel sorry for them. I have often wondered how they start? So I can keep it from happening to me.
