I don't have an answer to your question, but i have crawled around under a few of these and I'd suggest you consider fitting a transfer case PTO instead of the transmission PTO.
You will have more space under the bed than if you try to fit a front and/or rear facing Transmission PTO.
BTW, what size generator are you needing? I like the deuce as a work platform, but the possible inefficiencies of the big motor incorrectly matched to the load give me pause.
Best regards,
Rick
