Weird thing though, no airbag deployment!
From Wikipedia: "Unlike crash tests into barriers, real-world crashes typically occur at angles other than directly into the front of the vehicle, and the crash forces usually are not evenly distributed across the front of the vehicle. Consequently, the relative speed between a striking and struck vehicle required to deploy the airbag in a real-world crash can be much higher than an equivalent barrier crash. Because airbag sensors measure deceleration, vehicle speed is not a good indicator of whether an airbag should have deployed."
Did your rig have side curtain airbags? If you didn't strike something head on, its understandable that the front airbags didn't deploy... but side curtains should have on roll over.
Glad you and your family were relatively unhurt.
