So with the new 6th gear, does anyone know what the comparable final RPM's would be between an 05 with 3:73 and 265 tires and an 06. Pretty much what I am looking at is going with 4:11's on a one ton versus 3:73 for more pulling power if i can get good economy by that 6th gear.Thanks for any help.

There about a 200 RPM difference.
