Unfortunately 2.7 Fortuner is quite heavy and can barely pull itself in the sand,2.7L powerplant can be good only upto the beaches where help is at hand in case you need towing.In the desert and sand dunes this vehicle will leave you stranded until help arrives[if U R lucky].Even the 4.0 L can get stuck easily in sand unless it has Rear Differential Lock,standard Centre Diff Lock is not enough to get you out.You may be lucky if you dont get stuck even with 4.0L Prado.Depends upon your experience in Off Roading/desert driving skills.Centre Diff Lock is useless if one front and one rear wheel loses traction.
Good Luck.
