I experienced a car fire once, many years ago. It was devastating, and it was only the car. We would be completely heart broken if we lost truck and trailer under any conditions. I am sorry for your loss and extremely grateful you and your's are all OK. That's the most important thing.
Every time, before pulling out of the drive way before any travels with truck and trailer, my wife and I always say a little quick prayer, "Lord, get us there safely; and get us home safely." When we get home, pulling in the drive way, we always say, "Thank-you Lord!" I'll say, "Thank-you Lord for watching over TusonJim also and for giving him the wisdom to do the right thing at just the right moment!"
