To boldy go where no camper has gone before...

we do have something in the U.S.A. that do's what they do! we have the 4x4 van conversions and truck campers that will go any where they go with that trailer as well as a lot of places they can't.
years ago I took a truck camper on a chevy 4x4 places they could not go, but it is fun watching them

I agree 110%!

I think it boils down simply to economics. The Aussy camping trailers are probably often towed with their owner's 4X4 SUV-type daily drivers and the camping trailer by itself is probably a lot less $$ to own than a 4X4 van conversion that is not suitable as a daily driver. A camper plus a properly set up 4X4 pickup to deal with the camper is probably a lot more $$ to own than a camping trailer plus a 4X4 SUV-type daily driver, and the TC's 4X4 pickup may not be as comfortable a daily driver.

The trailer plus an SUV-type puller of course works in many situations, but is not optimized to the point where a 1-ton 4X4 van conversion or 1-ton 4X4 TC can be. BTW, a van conversion or TC can of course be made to stay out as long as a trailer plus SUV-type tow vehicle.
