The pinbox extends substantially forward from the visible bolted joint, so the hitch is not likely much behind the axle. Even if it is a few inches back, that would only make a few percent difference in axle load, although even that bit won't help.
It seems that in current full-size pickups the rear axle weight rating is high enough that the GVWR is likely to be violated before the GAWR(rear), so I wouldn't be too concerned about it.
