JMHO, Proper towing isn't rocket science. Tow chains have been around for decades, and would have prevented this tragedy, unless they were attached to something that tore off the van.
Trailer breaks are important. Maybe because I live in Austin with a lot of members of the "Anti-Destination League"... people who deliberately cause wrecks with bigger vehicles in hopes of an insurance jackpot. I don't see how someone can drive around an urban California area with such a big trailer without rear-ending another driver.
