Happy John, Totally disagree sorry! The ST-X 550 is the best 4X4 ute I've ever owned (its my 3rd). Fraser is sand driving, sand driving is sand driving! Anything will eventually get bogged at some stage. Most who sand drive, love to push it a little as soon as they hit sand to try get bogged. In fact, it's no fun unless you do get bogged!
I just took my 550 to Mount Pinnabar in the high country for her first major outing last week. No troubles at all, manual mode work every well and with the MTZ's plus tough dogs plus 170kw & 550Nm, she preformed as well (if not better) then my mates 120 Prado, my father-in-laws 120 Prado, my brother-in-laws Pajero and my other mates SR5 Lux. I loved my 07 D40 but old Black Betty had nothing on the new 550. Out classed in all areas.
