First time on the mojave trail. We were running behind schedule. First time my mom was driving an H1. My dad pushed my mom to make up some time by going faster. Hit a long straightaway, going about 60MPH. Long sweeping turn to the right was fine, short straightaway and then much tighter left hand turn. Took turn too fast, truck was understeering and headed towards going over a dirt berm a few feet high with cacti passed that. Mo mom turned tighter to avoid the berm and stay on the road. The rear end started sliding out, my mom slowly got off the accelerator and didn't hit the brakes. Unfortunately my mom had Cadillac Escalade at the time and reacts totally different. The independent suspension and no rear sway bar on an H1 didn't help with the oversteer from overcorrecting. Truck fish tailed at least 3 or 4 times. Truck ended up sideways on the road and the rear tires slid into the drainage ditch you can see the rear tires are sitting in in the pic. Rear tire gripped all of a sudden, sending the truck rolling sideways. Truck rolled at least twice. The rolling ended with the front tires on the ground and the rear tires several feet off the ground, when the rear tires fell back down it was with enough force to blow the beads on the rear tires.
Truck started right up and everything worked after the roll.
