The comment about the 3500 with Aisin constantly "HUNTING" and 3.42's not being good gearing.
If the truck is placed in TowHaul it won't hunt. Aisin makes the 3.42's work within it's GVWR because of the lower starting gears. When towing lock the trans in 5th it will be exactly the same RPM's as if it were in 6th with 4.10's.
Bonus is better economy running solo with 3.42's.
I towed 28-29K combined with 3,42's and only negative was starting on a grade. That would have been cured if I had the Aisin instead of 68RFE.
This post is spot on. I have 342s in my 2016 in sig and it pulls v strong, I've towed at 24k GCWR across three states and on job sites have gotten trailer with a small-medium 'dozer on it moving with no issue.
I bet it would be easier on your truck and drivetrain when taking off if you had lower gears...and I also bet there's not much difference at all in fuel economy running solo.
