Picked up my D yesterday. Love it, but today noticed the axle was a 3.55 not a 3.92. Talk to the dealer and he said he'll swap it out. Why they would build a 5.9L SLT + fully loaded including HDSG and trailer tow is beyond me. They should include the axle in one of the packages so it wouldn't get screwed up. Other than that I love the new D.
