It occurred to me when i was driving with the caravan, that it has gas tanks on the front, but when you crash nothing happens to them. It would be really cool if the exploded or at least caught fire.
I don't mean to be a party pooper, but propane tanks don't really explode in the way you're describing: http://www.propane101.com/explodingpropanetanks.htm I think it's a fun idea, but not quite realistic.
