From all the photos posted from folks sharing info about Australia, I get the impression that Australia style camping is far different than USA style camping.
First off, USA style camping, for the average person, is on developed property, developed campgrounds, with roads leading to select campsites.
It seems, everything I've seen from Australia involves back-country, off-the-road, sometimes...not even a road camping, where the terrain is as rugged as it can get.
That's why the RV are manufactured for robust and their counter park USA cousins. And it only makes sense that anything towing or driving an RV has the appropriate vehicle to do so. So yes, the Australian family of camping and tow vehicles are truly more robust than in the USA.
For comparison, I wonder how even some of the best tow vehicles we have in the USA would survive some of these locations in photos from Australia?
And I agree, a tow vehicle shown in any of those photos above in the USA would truly be an attention getter. In Australia, it seems to the quite common.
