Good feedback guys, I'm just getting acquainted with the various trim levels. That's too bad, because the Wagon looks really bada$$.

IdaD, I'm probably not to going to the Rockies with this truck/trailer, but there are some decent grades here on the East coast too. Anybody have the 4.10 gears with the 6.4?

I really don't understand why Ram offers the 8 spd with the 5.7 1500 and not with the 6.4 2500. They come in models that can easily handle the 6.4's torque. In fact it is the automatic option on the Hellcat which produces 650 lbft.


HP and torque are only part of the equation. I can put a cheap tranny in a 600 HP 1,500 LB dragster and it will work just fine for years. If I put that same tranny in a 600 HP 3,500 LB door slammer and it will oil down the track the first pass.

The same thing with car and truck tranny's. There is a BIG difference between a 3,500 LB car and a 20,000 LB truck and trailer!

If you've got 80-100k to burn, there's limited production Ram 2500/3500 available, look even more bad arse than the PW

They had one at the dealership I bought mine from, called the Prospector Edition. It was a 3500 Laramie CTD, upfitted by AEV with a ton of gear. Priced well out of my ballpark.

I have the 6.4 with 4.10, 2017 btw. I've never had shifting or performance issues, but my trailer is very small and light.

I don't think they're using the ZF 8 speed because they don't want to pay for it.
I have about the same weight TT and have bee giving this choice a lot of thought.
In the end I think I will go for the Cummins again. I climb mountain passes a lot and I know I would always be thinking "I should have got the Diesel". Price difference is nil over a Hemi because even a 10 y/o cummins equipped truck is worth the orig price of the diesel more when I sell. BTDT.
So the diesel ends up being a nearly no-cost upgrade in the end.

We have a 2016 RAM 2500 Tradesman crew cab, 6.4 hemi, 6’4” bed, 4 x 4, 3.73 rear. We tow 28’ almost 7000# TT with no performance or shifting issues. Hardly know it’s back there. It’s our only vehicle so we are considering trading it for a SUV and using my sons truck for towing.

I would look for a real clean GM 2007 Classic 3500 with the 8.1 Allison combo. Proven transmission and very simple, reliable, robust motor.

The real question is the drivetrain....I thought briefly about the manual transmission, but the traffic around here has gotten so bad I'm afraid I don't have the patience to shift anymore. After losing 2 automatics while towing, it seems to make sense though....


The manual is only available with the Cummins engine, not the 6.4 Hemi.

I don't know, the 8HP90 is rated for over 700 lb ft behind a diesel. Should be plenty good enough for the 6.4's 429 lb ft.

I have the 8.1 now....if I'm gonna spend $$ to get a newer truck, I would like it to be newer than 11 years old, I was shooting for 2-3 years old. Wish I had the cash for The Prospector Edition, that sounds like something I would love!

If set on a Dodge, great. I'd look at the GM with the 6l90 trans. Appears to be a way better trans than the 4l80/85e like you have. I've had nothing but problems with the 4l80 or its predecessor the TH400 behind BB or TD rigs.
The mega cab does look like the biggest crew cab option.
