Default I Like 3.92

Bill, I have several boats, the larger is about 3500 lbs like yours. I like the 3.92 for towing because with 22" wheels, the effective ratio is more like 3.7 which was my RAR of choice in older trucks with smaller wheels and similar tow ratings.



I think the question you have to ask yourself is just how much towing are you going to be doing? My towing mileage is roughly 60% of the total so I feel the slight drop in mpg is worth it. If you are towing only 30 or 40% of the time or less, you might be happier with the 3.21. It will get the job done and your mpg will be better.



BTW: as an average, I get about 16 mpg towing the boat and 21 highway solo if I don't put my foot in it too much.

As an example; my ‘12 Ram six speed with a 3.55 rear end turned 1500 rpms at 65mph. My ‘19 eight speed with a 3.92 gear turns 1750 rpms at 65mph, and gets better mileage both around town and on road trips.

I don’t have any towing experience with it yet, but I’m thinking it’ll be better too.

The ‘12 had 20” wheels. The ‘19 has 18” wheels.

I can’t explain it, but it is what it is...

Wheel diameter makes no difference; tire diameter does. If you have 33" tires on 22" wheels or 33" tires on 18" wheels the only difference is sidewall height and possibly weight.


3.21s are plenty for 3500 lbs.
