Rear seal leak on Cummins and need to pull Allison MD3060

I'll start by saying I am very mechanical, rebuild engines pull and install engines, trannies etc.
But my RV has an Allison MD3060 behind, rather in front of, a Cummins 230hp on a Winnebago pusher. 1993. Great running rig with a rear seal that leaks on the Cummins. The MD3060 is big. Anyone know the weight? Is this doable with a couple guys and a tranny jack? The job seems simple enough it's just the sheer size that gives me pause. Anyone done it and have advise? If I do trannies I usually replace the front tranny seal while it's out. Is that something I would want to do here too? Any specialized equipment other than a heavy tranny lift that's needed?
