The other issue with that PTO is that without a transfer case to put in neutral you can't use it while stationary. For the same reason there is no air pump in that position on a 15 CWT.
I see no levers on the floor for a two speed transfer case. I really don't get that PTO set up and what it could be used for, somebody might have done it and then got to the point of realization that w/o the transfer case it was useless.
