2500 to 3500 dually first tow comparison.
So I traded in the 2015 2500 for a 18 CCLB 3500 Cummins Aisin 4.10 and thought I'd share my experience on our first tow with our 5er TH. First off I didn't trade because my 2500 wasn't fully capable...

Thanks for the feedback. It sounds like much of the improvement is with the gearing.
We'll be buying a new SRW 3500 in a couple of years (when new non-EGR emissions come out) and I hope by then we can get a SRW #3500 with something more than the 3.42 diff.
With the Aisin, 3.42s work just fine. The big plus is cruising empty at low RPMs. 80 MPH is only 1750 RPM. If 3.73 would have been available I would have gotten them, I now know that would have been a mistake.
We have towed the high profile 16K 5th wheel to Arizona and back twice. Mountains, high winds and cities. Works great.
