New Duramax owner hitch question

I do have the block out in the hitch, but since I have the puck system I believe it's okay to do that. I am curious though if anyone is running the B&W puck system in a 6'6" GMC/Chevy with a standard pin box? If I have the clearance, I may just bolt the Revolution pin box in the fixed position and tow conventional with the pivot point at the hitch instead of the trailer. I know i could do this myself and check clearances, but thought maybe someone is already towing this way and could save me the time of switching everything over.
