2.7 Liter Ecoboost and 3.55 Rear ..5K Towing Capacity?

I would suspect based on ALL of the models listed in the guide. The dash in the space is a non optionable combo! IE the folks that say the 3.55 gear sets was/is not an option for that combo. Similar to GM, the 4.3 V6 only has a 3.23 option in rwd, but 4wd you can get a 3.42! The 5.3 has some similar available or not available options too! I'm not familiar with the Dodge ooptions, but will assume they have some similar availability options too!
