Can you expand your thoughts on your preference of the 3.21 over 3.92?
Quite a bit late for me to be responding. My apologies.
I prefer the 3.21 for these reasons.
1. The 3.21 seems more relaxed at highway speeds. I drive a lot of highway miles. The difference in RPMs is noticeable.
2. The obvious, gas mileage. I believe it was a savings of about 10% for me.
3. I don't tow anything other than a small 5x10 utility trailer. Even overloaded that does not add up to much weight. I probably use my trailer three times per year.
4. My stop light to stop light racing days have been over for about 40 years so any quickness factor is kind of wasted on me. Not even sure I noticed a difference.
I've really enjoyed both my 3.21 & 3.92 trucks. So I can't complain about either one. But my preference is the 3.21.
I put 55,000 miles on the 2014/ 3.21, I'm approaching 50,000 miles on the 2019/ 3.92.
