Seriously though, this is such a freak thing that there is no way the manufacturers can predict and build for it. I say he HAD to have been going more than 25 - 30 miles per hour because at that speed, you're just not going to have the force to flip a ~30,000 - ~40,000 pound vehicle end to end!
Your welcome.
I agree about the speed. They were also towing a vehicle behind the motorhome. I'm sure that factored into the motorhome flipping if the vehicle was swinging around. That cut-in-hill area in a bad stretch of highway, your either going up hill towards Northern Kentucky or down hill towards Cincinnati and the Ohio River.
