I couldn't view the 2nd video for some reason.
Anyway, on the first video, yes, SWB's are more prone to flip over backwards on steep climbs. That was a relatively gentle roll though, and chances are that Jeep was flipped back over and was not much worse for wear. Try that with a Hummer (or a Grand Cherokee, as to not discriminate).
Alot of TJ's run stickers on their windshields that are upside down and read "If you can read this, roll me over". I joke that Grands (and other SUV's) should have stickers that say "If you can read this, CALL MY INSURANCE COMPANY"
The 3rd video, it's called WATCHING YOUR SPOTTER. That was a clear case of driver error. The spotter was clearly directing him to the right, but the driver kept going straight. Wether he could see the spotter or not, it doesn't matter. If he couldn't see or hear his spotter, he should have stopped and stayed put until he got back into contact with the spotter.
