As far as vehicles, here's a pic. Remember momentum is your friend.
Yikes!

IMO
As when adding a lift, tires and steelie extras each truck is going to handle differently.
That being said driving it is going to be your only true test.
You have to put it through it's paces in every condition to see what it can or can't do.
At Hwy speed there's not much you can control so try not to put yourself in a bad situation.
With the articulation I have it feels like Im hugging the ground.
I've yet to have any scary moments.
You owe it to you and yours to experiment wisely while respecting the vehicle.

My guess is, for the way this T4R is set up, this is pretty dang close to a rollover.

Yes, I was a passenger in a roll-over, not once, but twice, and it was not really "off-road", it was in a field...damn Bronco IIs...

Had an FJ

Before my T4R, I would take my girls (young) out in the FJ. When we got to anything "scary", I would tell them to keep an eye on the gauge... so that if we rolled, we would have concrete data for the next time out... :-)

Just resurrecting this old thread... did anyone actually try this? Would be curious to verify the earlier comment that the 4Runner was designed to 42 degrees.

I think our interest in rollover is primarily at low speed, therefore we can safely ignore momentum effects and racetrack embankment analogies.
Rocks and slippage are big factors of course.

Additionally, a better way to measure the "pucker" angle would be along the diagonal axes of the truck (LR to RF and RR to LF) which would
measure the combined effect of pitch and roll. This video highlights the pucker:

Yes, the spotter is an idiot, but it shows that the pucker doesn't necessarily stop everyone.
