A LC isnt mandatory , a "lesser" 4wd would suffice , but some 4wd are not that ideal for the trip. eg the X5 , mainly from a tyre /wheel point of view.
Going further along the cost/capability line, then a van with reasonable ground clearance would do just as well. The 4wd thing can be a must depending on what you intend and roads/tracks you wish to traverse at what times of year . You also need to consider the tech level /fragility of the vehicle . HTSH
