That particular powerpoint shows the KC-767A for either Italy or Japan (I’m not sure which.) The area forward of the pallets shown is where all the mandatory bits will go. There is a forward door in that area, ahead of the cargo door.
There is also area aft, with it’s own aft door, so perhaps some of the permanent seating for 15 crew will be there, although with a full cargo load, they’d be cutoff from the forward part of the aircraft. (unless they were really skinny...)
As you can see from the A330 MRTT picture the ARO station takes quite a lot of space. The station reachs up to the forward doors. All three KC-767 pictures miss this station and the required seating in front of the station. Therefore the crew rest compartment have to be behind the forward doors then looking from tip of the nose.
“There is also area aft, with it’s own aft door, so perhaps some of the permanent seating for 15 crew will be there, although with a full cargo load, they’d be cutoff from the forward part of the aircraft. (unless they were really skinny...)”
On the Australian A330 MRTT the compartment is located on the middle row to keep both aisles free. With 8 economy class seats on both sides with a pitch of 30’’ a KC-767 lose at least the first row of pallets.
Now there is another problem. If the main deck cargo door is located right at the wing root, as it is slightly visible in your pictures, the main deck loader is located right in front of the engine. The loader can't maneuver much without touching the engine. To allow the loader a little space to maneuver I'll would recommend at least 10 ft distance to the engine. Then the main deck cargo door is located right within reach of the crew rest compartment. Due to crew changes during flight the crew rest compartment and the crew seating can't be located aft.
Position 3.2.3.3.2 of the SRD is NON-MANDATORY. I can see no other reason why this shouldn't be mandatory except the favored aircraft got problems. As you can see within the SRD everthing a KC-767 can is mandatory everthing else is a option.
