It's always different, you can usually feel it and get out of the situation before going over. If you're going too fast, or not paying attention to what your tires are going to climb or drop off, a meter won't make a damn bit of difference!
Right before this pic was taken, I had to put it in reverse and back out a little because the right front started coming off the ground...which is why my passenger got out and started taking pics! (That is way more unsettling in a van than in a Jeep!) The reason why I had to back up is because I couldn't turn any more to the left to point the front end down. As the right front wanted to climb higher, the left rear was not able to support any more of the load. Once I backed up a few inches (it usually doesn't take much), the front came down. I turned the wheel full passenger and backed up some more, then turned driver and slowly pulled away as my butt unpuckered.
However, in this pic, even though the right front is off the ground, we were in no danger of tipping over on this obstacle. This is because the left rear was getting ready to climb which puts the right front back on the ground.
It's always different. Know where your tires are and what they're going to do next...and go as slow as possible. There is an exception to the "go as slow as possible" part, but that's for the advanced class! Lol
