I don't know if this will have any relevance but here goes. I was an over the road truck driver for 27 years averaging 750,000 miles each year. During that time I witnessed lots of accidents just after the incidence. I never saw a class a accident, not saying there weren't any just none that I saw. On the other hand travel trailers pulled by vans, pick ups or suv's were a regular occurance. Almost every time the TT operator had passed me miles before the accident speeding and the trailer was wandering behind the tow vehicle. When I say speeding I mean over the 70 mph speed limit. If this has any bearing on the discussion, I don't know.
