Although some differences the Iveco Daily version of same engine is available as a download on this site I believe.
The main difference is being rear wheel drive the engine is not leaned over like the front wheel drive Ducato so the lower part of engine crank bearing carrier is different and obviously the sump and oil pick ups etc.
I have rebuilt several Iveco versions in the past, was there anything in particular you needed to know.
I have cam belt timing data and Technical Service Data/ torque settings etc.
Others on Forum will have more knowledge re the gearbox side and Motor homes in general.
