Ok, I'll chime in with my truck experiences over the years. We had an old beater '78 3/4 ton Ford that ran & ran, and we actually just sold it a few years ago. However in 1990 I bought a brand new 1/2 ton Ford and it turned out to be a lemon and I had to get rid of it just as I got it paid off. BTW all our trucks are 4x4's due to where we live, have never owned a 2-wheel drive.
For every day knocking around in the mountains we drive Toyota 4-runners. Our very first one a 1983 (I believe the first year they came out) is still running and one of our sons rebuilt the engine and it's still going. It also survived both of our sons' high school years!
My husband drives a 1996 4-runner for car pooling to work and it's never had any problems.
Then we also had a Toyota Tundra, and it was my favorite truck out of all. It had a great ride and did great in the mountains. Sadly it didn't do so well pulling our camper up the steep mountain passes. It did ok on the flats - but mountain passes really made it struggle. So traded it in for a Dodge diesel. My husband loves that truck - I hate it. It has an awful stiff ride, flimsy trim, and lots of small things have fallen apart on it, even though we don't use it much. I'm convinced that the Cummins engine will outlive the rest of the truck! But... it can literally fly up the steepest mountains with our Airstream camper!
My advice, drive all the models you like, then choose what suits your needs. No one truck will do everything well.
