Personally, I see 4x4 in an expedition camper as a mechanism to get you out of trouble, .....
I'd have to say I share this point of view as well.
Knowing what your driving on or into like a sandy beach or mud hole will go along way in saving you time, frustration and money. Everyone wants to camp at those far away remote locations we read and see pictures of, but once one starts jumping continents vehicle preservation should be foremost on a travelers mind. There's always the possibility of someone getting hurt in any vehicle extraction process. Hopefully its nothing more than a few cuts and some blisters, but it could be more severe like having a stroke or even a heart attack from the physical exertion.
