 Although my 2003 was great, the 2006 is even better! Being a King Ranch, the interior couldn't be better and this one has the moonroof as well. The overall build quality is better and the improved steering and brake system are impressive. The 6.0 liter Navistar diesel is even quieter with out the heavy hood insulation from '03 and the power can't be beat with the 5 speed torqueshift. This one turns less RPM at the same speeds with the only difference being 18" tires which should afford even better mileage than before. I averaged 19 with my old one which for the weight, mass, and power is fine with me. The improved message center is as accurate as it is detailed. The GVRW is 11720 and nimble.
