I'll only list things I can't change (other than the pump).
1) Didn't have a glitter bomb CP4
2) Had a more powerful HVAC fan
3) Had more viewable camera space on the 8.4. A disappearing until you touch it menu bar and take away the "Top View" "Rear View" header on the backup cam in reverse. Like really? That's those views? No crap, thanks for letting me know.
4) Was a Mega Cab (except for when offroad)
5) Had a smooth hood where the badges are so I could pull them.
6) Had a smooth tailgate where the Ram head is so I could pull it.
7) Had proximity keyless entry
Other than that stuff, and some is trivial, it's one of the nicest and most capability impressive machines you can buy. I daily it, towed with it, offroaded with it, took family trips in it, pretty much all you can do with it. Gets great mileage, comfortable smooth ride, great interior and sound system, awesome configurable gauges...etc. Fantastic super truck.
