I've had well over 50 vehicles, not nearly as many as some guys here

, but still a lot. The most trouble free car I ever owned was my Camaro SS396. I hot rodded the crap out of it, kept it for 5 years and then sold it for more than I paid for it. I think we could all only hope to get that from every vehicle.
Through the mid 80's and all through the 90's and early 2000's, I had several employees in my carpentry framing business . We ran at least 15 F-250 & 350's gas and diesel trucks. Looking back, they cost too much in repairs and too many parts wore out prematurely, but I still really liked Ford trucks.
About 5 years ago, it was one of my employees that actually got me to consider trying GM. He had a 2500HD Dmax/Ally he would plow snow with and tow his boat. When he got up to 230,000 miles on original motor & trans, I was impressed and convinced. I couldn't get a Ford to go 150K without at least 1 or 2 replaced transmissions, 4 sets of ball joints, steering boxes, etc.....
I'm still hanging on to a '89 F-150 for a spare truck. I still think Ford builds a stronger chassis truck than GM or Dodge, but that's about where it ends. They change their engines & drivetrains too much for my liking compared to GM & Dodge.
I disagree with the premise that trucks of the past were "pretty much the same". I think they have pretty bold differences, but recently they are heading more towards being more alike than different.
Most have comparable tow ratings, GVWR's, ex brakes, gradient brake transmissions, etc.
