We've taken stock open IFS Toyota's through there, it is a very long climb out of Lockwood Valley just keeps going up. This section is a little tricky but if you take the right line there should be no issue such as rolling. As you can see if you take the correct line like I did in my old Sammy and TurtleTruck did in his 4Runner you lean heavy but don't even lift a tire, but if you go just a little to the left you have a problem. I sure wouldn't want to have put that Hummer back on its wheels there, that is a very steep hill and it is very long one mistake and it would get real ugly.
