I could be wrong, but I feel like with lockers, that looks like a hill that could be crawled up.
It appeared to me as if he did have the front locked, just stalled it. We all know how pics and film never capture the grade of an obstacle. And looking at the loose gravel, dirt, combined with washouts, it more than likely got to steep to hold traction.
I don't see how you can bounce that much if you are properly aired down.
Here is a truck in our local club aired down to 12-14 PSI. Check out the air at 12 SEC.
The only reason I'm posting this is that the accident in the first post reminds me of this climb.
I tried to climb it several times. Walked it, scouted it and then tried to crawl it with just A-TRAC engaged. I tried that 2 times with no luck and had to carefully back down each time. 3rd attempt was with A-TRAC and DIFF locked and some speed. But didn't have enough momentum to get over the first obstacle (12 sec) mark. And there was a big root sticking out of the bank I didn't want to sacrifice the side of the vehicle to make the climb.
Anyway, this 80 makes it. He's locked up and after several failures by many rigs including 40s, FJCs, 60s, 80s, he gets it. He does sacrifice a tire towards the end though.
Not trying to argue here but when people watch this video, they will judge and say too fast, no control. There was one way up this hill and that was it. It was very steep, combined with big rocks, loose rocks and debris.
