Yes, but not all ladder frames are identical. Here's a Ram 1500 frame vs the Wrangler frame for reference.I'm just saying that pretty much all ladder frames are built that way and there's no real way around it. If the other vehicles don't exhibit the behavior and have a very similar shape....that's not the underlying cause of the tip over.
You'll note in the slow motion portions of the IIHS video of the wrangler that the tipover does not begin until the vehicle hits that point where the frame widens out. A better bumper could help out in this situation I'm sure, but the shape of the Jeep's frame does appear to be a contributing factor.
