Us trailer users seem to put wheel bearing/tire maintenance on the back burner ! Personally, I am fastidious about that as I've seen and helped out folks a lot over the years when bearing failures schitt happens. Even still, I've had the hot/burned bearing bug hit me at the most unexpected times.
I'm thankful that Jimmy had the awareness to see that fire before it got really bad and the fortitude to get the FUEL out ! It coulda been a LOT worse
It'd be interesting to know how the fire started in that video. I try to learn from others' misfortunes and take precautions to lessen them happening to me.
These two fire events make me wonder why onboard fire suppression systems in the enclosed trailers isn't a good idea. Sumthin' to think about......
