which Axle Ratio for EcoDiesel

What axle ratios do you folks have on your trucks? I was dealing with two dealerships in trying to place a 2014 Longhorn order this past week. Both said that the default axle ratio is 3.21 on their order page. I told them that ratio is for the V6 gas and the diesel is 3.55 with option of 3.92. They both said can't do anything about it. I placed an order with one of them. What do you think I will be getting? What is the true default axle ratio?
