getting a diesel powered vs. v10 really dosn't matter, In my experience you can get a really nice v10 pretty cheap vs what people want for a deisel powered.
mounting the engine is easy if you get the mounts from autowold, 12v's are really simple. you will transplant the sensors from the ford engine to the cummins to make the gages work and you will need a tach kit from autoworld or destroked
the trans you want is the bad part, the 47rh is a good boat anchor right next to a 6.0 psd if you tryign to avoid wiring a nv4500 is the best or reuse the 4r100
here is a link of an excursion built using the common rail and a 48re that started as a v10
