Thats great for you... I bet you even use the stock oil plug.
I go by the "stitch in time" method. I never have to undo the axle cover bolts again to change the fluid.
Being that time is the only thing of value in life... hence why I went with an inexpensive cover with a drain bolt.
Next time I service the rear fluid it will take 7 mins instead of 40.

There are no inexpensive super 8.8 ones. Well, $250 if you consider that inexpensive. The 9.75 has more choices.

I run heavier viscosity engine oil (5w40)
Trans I swapped the Dorman pan and do a service every 30k with a filter every 60k. Drain plug makes it easy. Pull plug, let drain, replace plug, add in 4-5qts and start truck. Finish fill with truck running. I also have an engine bay dipstick so it's easier to fill. Nearly $200 but worth every penny. MercLV equivalent (aka NOT Motorcraft)
Rear diff I run a cover with drain plug and a LubeLocker gasket. I do rear diff fluid every summer. I just use Valvoline 75w140 easy fill packs. The argument is there for removing cover and wiping up extra garbage but I service often enough I'm not overly concerned. I also use blue Loctite on the diff cover bolts after having 3 of them loosen/fall out. The cover is a B&M girdle cover so it is subject to more vibration than stock. YMMV
Front diff, about every 50k. I don't use 4x4 a ton and never 4AUTO. 75w140 Valvoline easy fill packs+fluid extractor.
Transfercase 50k because, again, hardly use 4x4. MercLV equivalent
Coolant I did with a water pump and converted from Orange to Motorcraft Yellow.
The only thing Motorcraft I use is the coolant. None of this a recommendation. I offer no responsibility for variation outside of Ford recommendations, just sharing what I do
