Oh, and his insurance company probably won't pay off on this as he had improperly stored the tank in the vehicle. (Generally they are verbotten in the passenger compartment and there are rules and regs on the proper transportation of said tanks.) He failed to follow them. As they could claim that by having the tank he was using the truck as a commercial vehicle. Yes, that's a skinnier branch on which to hang their hats, but they have list all the reasons to deny the claim.
That's a nice paperweight he now owns. I'm sure the finance company will want their money now.
