Which axle ratio for 2013 Ram 3500 dually?

Is it even possible now to select a given rear axle ratio with the way the manufacturers "bundle" options and features? For example on my '05, the truck came with the "tow package" option, which meant by default, it came with the 4.10 rear axle, no other option.

The only thing this discussion has done is make me wish Ram offered a 6 speed tranny earlier than they did...............:R

I didn't option them up but from the spec sheet, it said for 3.42, you get roughly 20k lb towing, for 3.92 (?), you get roughly 25k lb and for 4.10, you get just under 30k lb.

EDIT: the middle gear should read 3.73, not 3.92.
