1. You keep making these claims about the F150... Yet you seem to be lacking in the proof department. I have owned both and had 2 F150s as work trucks. Can you speak from the same experience, I'm guessing the answer is no.
2. The Tundra has a longer 60-0 stopping distance than the F150. As someone who has owned and towed with both trucks, I can say with absolute certainty that the size of the rotor is irrelevant, the F150 has better brakes. I never once said that the Tundra has a problem stopping, rather the F150 does it in a shorter distance. In fact, all I have said about every difference between the two is that the F150 is better, I never once said that the Tundra was subpar. The Tundra was a great truck when the second gen came out, now its just average when compared to newer designs.
3. The motor in the Ranger has a forged crank, rods, and pistons. The block is extremely dense and the cylinder walls are very hard. The head bolts are spaced very close together and the cooling and oiling systems are phenomenal. I'm guessing that you have zero first hand experience with them and have never once contact a company like Brew City Boost to see exactly what those motors are capable of. There is no shortage of modified Mustang that are beat on as daily drivers and have zero issues. Im fact, I know of one running low 11s in the 1/4 and the guy drives it to work Monday-Friday.
4. When it comes down to it, a small army of engineers and lawyers felt confident enough to sign off on the capabilities of the F150, I'll take my personal experience and their willingness to accept liability over your "word" any day.
