Thats the kind of trip we bought her for. I've owned a toyota hilux and a toyota landcruiser, (and recently a land rover 130), but this is what we settled on for a long trip...we've spent our time in roof top tents, sleeping in the back of a ford van, ground tent, etc, but for an extended trip, the comfort and safety and the ability to carry loads of food water and fuel was why we chose her - and their fantastic off road ability. There are concerns about a top heavy vehicle in sand (and other situations), but you've just got to take that into account when driving.
Short answer - its what she's made for!!
