Weight of a 2004 2720SD?

I didn't know about this issue myself, so I consulted my owners manual. Attached is the relevant portion.

My specific vehicle:

GWR = 6,600 (presumably the GVWR, taken from the sticker on the door jamb)
Towing capacity = 6,500 (from the manual)
GCWR = 11,800 (from the manual; this is not the sum of the above 2 numbers; I'm not sure why.)

To me, the stated GCWR seems to imply that adding cargo to the TV does not subtract from the towing capacity.
