I wonder how many pick-ups in Texas would have better control if they could just hit a 4 HI button when it started torrential raining.. you would then have to ask how good the tires are. But even then, it would have helped. (Even the selector on an Expedition has that option. At least on an Eddie Bauer it did. And that's maybe the single best snow vehicle I've ever had. I believe weight helps, yes.)
Back in Upstate New York.. we would laugh at pickups that were not some form of 4WD. It was almost like a luxury item, sure, but if you're gonna get a truck.. get one with 4WD? Just as an aside. And the farther North and West you go in NY, seems like the more snow you get, or got. Some debate about winters now. They used to be very bad.
I still think my original statement more or less nails it. Sure, large swaths of owners in desert states may not need 4WD... Really, ever. Sure. But now take that truck to Upstate New York or Pennsylvania in the winter to visit your family member that just got a house up there or whatever for Christmas and your Texas plated truck.. may encounter a snow road.. who knows.
Now, another angle. Are we talking about simply basic trucks, or basic
work trucks? I think an 80s Nissan P'up or Pickup (I do not think they had an actualodel name back then. Same for Toyota??) Or again an 80s Toyota Pick-Up were "basic trucks" and could be had with a 5-speed and nothing else in them.. cloth seats, maybe even no A/C. (Think Marty McFly's pick-up at the end of the first movie. That was a basic truck with a nice paint job and big tires. Looks good, even today.) But I am not sure if that is a
work truck.
I have seen Auto parts delivery vehicles be both basic Chevy S-10s and sometimes their Isuzu clone (????) and Ford Rangers. You could get an S-10 with a 2.5 and probably even a manual.
