We towed our 24' travel trailer and now our Maristar with a 2003 Lexus GX470. 6500lb is the rated towing capacity when outfitted with a frame mounted hitch. Funky exterior looks (IMO) and a bit short on wheelbase, but cushy, roomy, AWD, and mechanically bulletproof (so far, knock on wood). The motor is rated at something like 260 hp, but closer to 300 ft-lb of torque. As long as we don't get into races with Turbo Diesel American trucks while traversing mountain passes, it does just fine.
