Actually my AF (2011) doesn't have the sculpted corners. There is a radius to the front cap where the sides are about 4" back from the center which might help a little. It's my understanding that the Andersen hitch distributes the weight of the pin across the base of the hitch which sits pretty squarely over the axle. That's the theory, anyway.
As gkainz pointed out above, there are some configuration options that would let me tune the distance to get it as far forward as possible without risking contact with the cab. There are also concerns for contact by the pin box with the bed sides and tailgate that have to be considered.
