Gina: Apparently there was an interior leak in the
propane system, and a pilot
light inside (fridge, freezer, stove?). The gas built up inside until it reached the flame, then POOF!
Truck and camper were totalled, and that melted fiberglass roof looked very, very sad.
Fortunately, the shiny new truck and FG camper were owned by Ford Motor Company (corporate PR) and on loan to us for a film we were making in Montana.
I just went back to the dealer and got another one off the lot.
