This is an "oh dang"

I think they're assuming a lot too. How can a spark get all the way through a long exhaust system that probably doesn't even have a strait through muffler?

Well, the story did mention an "exhaust system failure."

The story also said: "... firefighters continued to squelch hot spots, investigators swarmed the Pace Arrow, crawling under the motorhome (sic) after a tow truck lifted its front."

So I guess they took a look at it and then started the assumptions.

I wonder if they even started the motor home to determine if sparks were really coming out from it?
