Most of the modern crop of dual cab utes and family friendly wagons are fairly similar as far as capability offroad.
Mostly similar suspension setups, ground clearance, offroad angles and component strength all combine to determine offroad ability.
Obviously the Utes are designed to carry more of a load and oriented to more work duties.
Most the IFS vehicles are limited to their capability by design with many somewhat aided by electronic driving aids to overcome some their shortfalls.
And as has been already said, many of these vehicles are not as tough as manufacturers would like us to believe. And many of them are nowhere even near the tough mark.
There are not many "hardcore vehicles" available straight out of the factory and only a handful of others which can be easily modified to confidently be able to take constant offroad abuse and hold together.
But, generally most people don't need a vehicle that needs such strength, and everyday onroad comfort and towing performance is more of a priority hence the compromised design.
Oh and in my opinion the best vehicles for hardcore offroad use are: Patrol Wrangler, defender, 76 series cruisers.
They are a step ahead offroad.... But a step behind on road
