Transmission/Axle Type
I have a 2004 E450/V10 motorhome - serial number 1FDXE45S84HA12689. My question is: What type of automatic transmission do I have (4R100 or 4R70/75 E-W) as the transmission fluids are different? ...

You have the 4R100 transmission.
If you're changing the fluid and the internal filter, be aware that there are two different transmission pans for the transmission, a deep and a shallow version, and the filters differ based on which pan style you have. You'll almost certainly have a deep pan and need the corresponding filter. The parts lookup at many auto parts stores might not know the difference or only have the shallow one in stock. Verify that the filters match up (particularly with regard to pickup tube length) to make sure you get the right one.
As for the differential fluid, I think it's a lifetime synthetic fluid...at least it is on my '98. It's the 4.10 rear end, if that helps.
