Jeezus. It's hard to imagine that was a toy hauler, there is next to nothing left. That is scary.
I think about fire danger quite often, it was a huge deciding factor in going to a residential fridge. This was started at the battery compartment tho, so I wonder what went wrong? I doubt there is any way to figure it out now, but definitely makes me want to ocd check even more things before a trip.
I am glad everyone is OK, but even then, that really sucks.
