In the old days, Mongolians would sleep in a yurt. Now, a six-wheel-drive RV is the hunter’s movable habitat in the steppes. Well, for two Mongolians. A couple of big cheeses in Ulan Bator have each bought a Mercedes-Benz Zetros 2733 vehicle. A diesel-drinking 7.2-liter straight-six delivers 322 hp and a gargantuan 959 lb-ft of torque to three axles. The high-class appointments include a shower in a bathroom that has a heated marble floor, a gun rack and two big flat-screen TVs—one in the lounge area and one in the bedroom. So there’s no excuse for missing “Live with Genghis & Kelly.”
