So then tell us…. If what you say is so true
It's not "if", it's not my opinion, it's a mathematical certainty.
The two trucks have a different tow rating on paper, due to the 3.92 being able to accelerate faster from a dead stop. Two of the J2807 tow rating tests deal specifically with 0 to 30 and 0 to 60.
So yes if your complaint is that you can't accelerate fast enough from a dead stop then I would say the 3.92 is the better option vs the 3.21
But that's not the complaint, read the first post, he's talking about RPMs at 62 mph and how trucks are passing him, the 3.92 won't fix squat in that case.
Take the 3.21. Remove the 8th gear and replace it with a deeper first gear. Boom, now you have the 3.92. You still have 8 gears but the other gears in between haven't changed, you still have the same towing performance on the highway (which remember the context of this thread, is the complaint of the OP).
Finally, if you actually had any experience towing with a 3.21, you'd probably discover that the 3.21 has no problem in accelerating from a dead stop. It has tons of power there. Where my truck feels less powerful is on-ramps and passing truckers up a hill, both scenarios you are well out of first and second gear so there is no difference between 3.21 and 3.92 at that point.
You guys get hung up on the 3000+ tow rating difference without understanding why and how that rating was determined. It's all about the first gear. If you're not in first gear (and somewhat second gear), the tow rating is identical at that point.
