I always get a chuckle out of these "4X4 vs. 4X2" threads (by the way, a "2X4" is a piece of lumber, not a vehicle).
In my 60 years of driving, I have owned both. In fact, I now have a 4X4 Dodge CTD 2500. I have had it in four wheel drive to test the function, but that is all.
I used to have a Jeep Rubicon. The only time it was in four wheel drive was on trips to Moab to run the slick-rock trails. Oh, wait, I did put it in four wheel drive, and locked both differentials, to try to bust a snow berm that I had built up in front of it. That didn't work, I had to dig it out!
When we were full timing in a triple slide fifth wheel, I had a 4X2 Dodge 3500 CTD. Never needed 4X4. After we settled, I used that truck for hauling hay for our horses, never needed 4X4. I took it to CA to pick up a car on a flatbed trailer, towed that rig across Donner Pass in a blizzard, did not need 4X4. Yes, I had to put chains on.
The only reason I have a 4X4 now is that a Dodge 4X4 is towable four down without modification (the 2500 CTD is too heavy, though), and 4X2 trucks are hard to find.
My last truck, a Dodge 1500, was 4X4 for the same reason: Towability!
I grew up and learned to drive in Northwestern Montana winters without 4X4. They were quite rare back then. Very few people wanted them!
IMO, based on what I see around here, 4X4 is more a "fashion statement" than a true "need"! Most of them rarely leave hard surface roads. Note I did not say "pavement".
