I recognize all those obstaclesNo, if you prepare your Jeep for water fording, none of that will happen.
I'm comparing it to this:
Some Jeepers on the video are hard core-wheelers, but many others are the regular Jeepers "off-roading and going way off the beaten trail and rock climbing"
You can add a roll-cage, a 5-point harness and wear a helmet, but that may not guarantee you coming out off a roll-over in one piece. But I guess for you, your engine is more important than getting hurt. Makes sense.
