I have to say this abt the Hummer though. Not one time, not once, not ever, did I feel I have put my family in harms way. As long as they stay seat-belted inside the H2, I'd prob feel safe even if the hill was spewing hot lava..
The Hummer was so comfortable in fact, my kids actually were asleep from 7pm and slept through every boulders in Big Sucky Sluice (including the tire change) till morning'ish of the 3rd day when they had to pee..
