I guess I have to call BS on this conclusion. It says that the 4 Runner is the worst at 24.6%, but then goes on to list the Wrangler at 27.9%, and the Nissan NV3500 at 30.6%.
Most all of the SUV's that are off road capable are high for ground clearance and are top heavy. It only stands to reason that they will tip more easily. These things were not made for Le Mans.
And of all on the list, the Wrangler and the 4 Runner are the only ones in their class as far as frame-on off road vehicles go. So maybe the headline should be the 4 Runner is best in it's class as far as roll over goes, because it is better than the Wrangler.
