My last 2 trucks have been open differential. I've never had a problem. I live in Minnesota. I use Auto 4wd when it snows. I don't know why people make LSD sound so awesome ? Like u said, they probably don't even know when it's working or not. I could see it being a more important feature if u have a 2wd truck, but then I don't understand why anyone would buy a 2wd truck ? Also I would never buy a Ford for the simple fact that u have to buy a Lariat or higher trim to get Auto 4wd. That should be standard on all trucks. Would never buy a Rebel either, for the same reason.
2 wheel drive trucks are cheaper to buy, maintain and run (mpg). Lighter weight means a little better hauling and towing. Finally, less FCA parts to go wrong.
I got a great deal on my 2wd because like you, most people in Ohio want a 4wd truck. Mine sat on the lot for over a year and a half.
With how far tire technology has come, along with all of the electronic driver aids, if you stay on the pavement, 2wd is fine for 99% of driving where I live. For the 1% of the time after a big snow, I just drive slower.
For people in the South, I'm sure there are some guys who think you need 4wd for the rain or grass clippings in the street, but others who would rather spend the money on something else. There aren't many places that snow like MN!
Also, I prefer the feedback of the rear wheels breaking loose on a slippery surface when accelerating, rather than finding out the road is slick when slowing down or turning. It's a nice warning to slow down and be careful. If 4wd helped with braking on ice/snow, I'd be more interested.
