This is definitely something I miss about the 3rd gen now that I sold it for an 08. MPG is amazing for a 4x4.

What’s the gear ratio code on your door sticker? I didn’t think they made 3.73 ratio for auto 4wd

EDIT: said 3.90 meant 3.73. Oops

You sir are correct. It's probably 3.909. I copied someone elses post for the format and pasted the wrong ratio. I'll look at the door sticker to confirm later. Updated my post.
