Regarding the above Jero pic, just to put things in perspective, this is the famous Bara Pani crossing in Deosai. This Jero has electronic suspension and height control, and before the crossing the height was raised to max which is good few inches above the standard height, and still you can see the water level is almost reaching the top of wheel arches. And also as you will see from the vdo posted in the last few pages the jero engine was being revved and it was spinning tires furiously at this stage looking for traction to keep the forward momentum going!
