Saw this today in I-96 outside of Grand Rapids, MI today. No ambulance so hopefully everyone was OK.

earlier questions rephrased, and more questions:



If the TV initiates a turn, even an abrupt one to avoid something for example, the Hensley is going to allow the rig to bend at the hitch like it is supposed to, right?

If, during this swerve manouever, the TV piles on the brakes and the brake controller is any type that does not brake the trailer instantly, the trailer could push the Explorer around into a jackknife, could it not?

A Hensley didn't help this guy either. $300 hitch with good safety chains


OMG - it's a dually! High winds, high winds - no fix for that. We owned a Hensley, drove thousands of miles with it and it performed perfectly. DH was a good driver and we never encountered a situation such as any of these. Well, we did encounter high winds but we pulled over. Any number of things could've happened in both of these situations and I'm not going to speculate one way or another.

Well, I can identify a blob of orange, but beyond that...

You can see the orange hitch under the truck. The front of it is pointing almost at the camera.. Also you can see the spring bar jacks on the A frame.

That's exactly what happened!! I saw the whole thing!!! :B

They'd be saying the same things it if were a 4x8 Harbor Freight utility trailer with two sheets of plywood on it.

Amazing how, from one picture, so many assumptions are made. We should all become forensic crash investigators. Would revolutionize the police department operations worldwide, as we could simply have one picture and know EXACTLY what happened.

With that being said, unless someone gets hold of the accident report, no one has any idea what caused the crash. For all we know, a moose was run over, wedged itself under the front wheels of the Ex, thus no steering. No steering is typically frowned on, so the Ex drive should have installed a moose catcher on the front of the Ex.

As long as their are trucks of any size pulling any size of trailer, there will be jacknifes. Period. Could a dually pulling that airstream possibly have kept it from crashing? Yes. Could a dually pulling that airstream possibly have crashed? Yes.

Making blanket statements about a crash with hundreds of variables simply doesn't work.

Agree on all the psychics and armchair CSI accident investigators.
Without more details we have no idea what happened.
I guess we can all just take a wild guess.

agree with John and add that many folks take an absolute position on
all things....AKA 'one size fits all'

Or that the OEMs employ COTS and corp parts bin in their designs
