IMO, it's not likely there is even enough hydrogen in the refer to do much more than blow the access door and roof vent off the coach. Even if there was, the area where the gas would collect is relatively small, well ventilated, and fairly well separated from the interior of the coach. An explosion like that would have vented outward toward the exterior anyhow. It's entirely possible a refer explosion could result in a fire, but I seriously doubt the explosion itself would hurt anybody inside the coach. I agree with the other guy that said it was most likely an LP leak. And it would have had to be a MAJOR LP leak to blow the place up. Fire investigators should have been able to determine the source of such an explosion. Tim
