corp 14 vs D70 vs D70HD DRW?

does anybody know what RPO options had to be selected to get the different axles? I keep reading that dually's have regular corp 14 bolts, but my truck has a D70. Is the D70 specific to the camper special package?

and how can one tell the D70 and D70HD apart? I think mine's a 70 HD but the tag says rear axle rating: 7500, which is the rating for a 70.
