I've never driven a Wrangler, and I wouldn't want to drive one long distances at highway speeds. But I have cousins who do that, so maybe it's not so bad.
It's a 4Runner for me.
That sounds similar to our 5th gen. Which has been enough power for whatever the kid uses in the back seat.
But you can carry a portable power source if you need more power.
At six feet, and with the driver's seat at its highest, I'm glad that the moonroof gives me an extra inch or so before my head reaches the sliding panel. Both the 3rd gen I had and my current 5th gen.
Whoever wrote that needs some remedial English lessons.
I suspect that, "eventually a decline in ... stopping distance", is the opposite of what was intended.
I really don't want to hear the engine at all. Engine noise is merely a necessary evil. (I'm certainly not going EV.)
Having said that... I enjoy hearing the growl of my wife's supercharged Jaguar F-Pace.
We bought our first 4Runner SR5 in 1997 when we lived in San Diego and frequently went out to Anza Borrego. The part-time 4WD and intermediate tires (balance of on-road efficiency and noise vs off-road grip) always worked.
Now we're in Arizona and our 2010 SR5 with the same level of tires...
That's a concern I have as well. But I think if you're ever out in the wilds with a flat you don't want the spare underneath the vehicle anyway, so hang it off the back.
The narrower vehicle can generally go more places.
Wheel base can play a factor as well I suppose.
I haven't been to Moab, but here in Arizona I think the most intense off-road trail I've taken my 4Runner is Broken-Arrow trail to Chicken Point in Sedona. That will be my test of the 6G.
