Well for starters, that propane tank under the van is basically a bomb!

I live in snow country. We get some big snows, like sometimes  4 to 6 feet
in 24 hours. Many houses use propane tanks. Occasionally the weight of a big
snow will shift a propane tank and cause one of the fittings to crack. The
propane will leak out of the tank, travel under the snow and get into the
house. When it reaches one of the pilot lights in the house....
Kaboooooooom!!! End of house. And end of people if they are in the house.

Scenario 1:
Well, imagine an accident that cracks a propane line or the tank itself....
Kabooooom! End of Westy! And end of people if they are in it.

Scenario 2:
Your propane flame does not blow out on the freeway. But being absent minded
like me you drive into the gas station and forget that it is on... under
certain circumstances (perhaps rare, but they do have those no smoking signs
on gas pumps for a reason)... you can imagine the rest.

Scenario 3:
Your propane flame does not blow out on the freeway. You don't get into an
accident. And you are not stopping to fill up with gasoline. But you perhaps
you are absent minded like me... You stop to fill your propane tank. The
attendant forgets to ask if your pilot light is off. You forget too.....
Kabooooooom!
