I have an F350 on order (getting built end of Sept!)....it'd be great if it approached the reliability of my 2012 Tundra. My Tundra has ~165k miles. It still drives great and feels 'new'...nothing loose, no play. We tow a lot with it. 5k lb horse trailer to 8k+ lb tractor. It probably has ~40k miles towing.
I needed a 1 ton to pull a larger horse trailer and I'm excited to get the F350. If I was buying another 1/2 ton, it'd be a Tundra... We also have a 2012 Sequoia (140k) and a 2014 Camry (180k). Both have been rock solid as well. I tend to keep vehicles for a long time, so I can care less if the auto maker does a re-fresh every few years....I look at cars/trucks for what they are, a depreciating asset that gets me from point A to point B, and for that Toyota has been great.
