I now have 4000 miles on the new 2006 and love it. I am even learning to live without some of the add-ons I have on the 1998. 5 (US Gear OD not available for G56, spare tire located auxiliary fuel tank no longer available from Transfer Flow). Unfortunately, I really miss the 2W-low switch from BD which they say is not available for the 2006 because of the complexity of the electronic shifting to 4WD. Has any genius out there figured out a way to defeat the front axle lock in while still shifting into 4LO??
