Well, now the Grand Cherokee has a unibody construction. I don't know I'd call it a crossover, because it's one strong unibody- you don't find unibodies with tow ratings of not quite four tons. You sure don't find that with the ability to run the Rubicon Trail.
I believe the Grand Cherokee has always been unibody. But I remember reading somewhere that they call it "uniframe" or something like that because it has something resembling a light-weight ladder frame built into the unibody chassis. Either way, it's definitely not a traditional body-on-frame like they used to make them. But it does seem that the Grand Cherokee is moving closer to crossover status with IRS now. If you want a true ladder frame and live axle rear in a mid-size SUV, your choices are extremely limited. The 4Runner is one choice and I believe the Xterra is another. Off the top of my head, I can't think of any others.
