You can make anything go off road, it's just a matter of how you modify it. From the factory most four wheel drives in this country are little more than hill hoppers and highway trucks, even the big F series and Dodge's, while bigger, still wont tackle a rough track unmodified. We have too many road laws to modify them like some of those trucks in the US that need a ladder to get into them. But anyone serious about four wheel driving still puts anything up to a 5 inch lift (total lift tyres, suspension), strengthens everything underneath, adds diff lockers, bead lockers, new ECU's or tuning chips, some even go as far as changing out the engines and gear boxes of a new vehicle.
A factory four wheel drive is okay for a bit of weekend sand driving, a bit of small rock hoping and a few river crossings, and a factory four wheel drive can go further in skilled hands than some modified four wheel drives go in unskilled hands but pretty much anything listed above would not last five minutes in garages here without being modified if the owner wanted to actually use it as a four wheel drive.
Pretty much every manufacturer has someone willing to bad mouth them because of bad stories on the internet. But turn up to any four wheel drive meet here and you'll find every make and model represented and everyone one of them goes hard, but the only ones that survive are the ones that have been modified properly.
