Director of Adventure Management Operations
My truck is the opposite end of the spectrum, 50k and not a single problem. Had two recalls (door latch and seat belt tensioner) which were minor.I would guess the biggest reason is reliability.
I have an 07 Tundra and 18 F150. After having both I would definitely get the Tundra. The only reason I didn't get another Tundra is because as several have mentioned the Tundra is in long need of an upgrade. With that said, if you don't ever tow and don't mind less reliability then go with the F150. If you want more info, go to https://www.expeditionportal.com/forum/threads/ittogs-truck-camper-build-was-6-x-12-trailer-conversion.199414/post-2780343 to see where jnich77 and I were discussing the two. I don't recall discussing reliability in that thread so my quick comments on the two is the Tundra has had one recall and one failure, idler arm. The F150 has had, I believe four recalls now, a failure, and three or four issues that Ford hasn't been able to resolve yet. As far as I am concerned the F150 is a lemon. But, with that said, the creature comforts on the F150 are far superior to the Tundra and that is why I still own it.
Even stock my 2.7 out pulled the 4.6 or 5.7 in either of my Tundras, especially when you start to gain altitude. Modded it's not even a comparison, the 5.7 is not even in the same league.
In the end, both are "good" trucks and it comes down to personal preference and how thick your wallet is.
