What’s the street word on both of these? Stay with the standard or go with the HO. Going be pulling a 41ft 5th wheeler at 17,000 GVWR

The "Old School" saying growing up was there's no replacement for displacement wink. If your pulling up a grade into a head wind the little bit extra power will be welcomed.


When in doubt SET THE HOOK!

I assume you’re talking about brand new. The HO comes with the Asian (might have misspelt that), which is a slower, higher torqued take off. Requires a bit more maintenance on it.

The HO will have the much better and beefier Aisen transmission.

With that said, get you a Duramax.

IF you want worse fuel mileage, and higher maintenance cost with a lesser quality truck to go with it, than the above referenced Duramax is what you need. If not than the H.O. which is only available on the 3500 will pull anything you hook up to it. I own both the standard 6.7 and the H.O. and can barely tell a difference.

Had them all every brand. If you want a dually then go HO if not the original will be fine. Neither will win a race against a Ford uphill. The air suspension, engine braking and interior are far superior then all others. Once Dodge finds another transmission that is 10 speed then it will be the king of the hill unquestionably. Ford will smoke a Dodge in max towing uphill, thanks to that transmission they have. Other than that you will be bumping your brakes frequently and better hope you level your load properly as their suspension is a bit squirrely at max load. End of debate, I have spoken.

I don't buy into the Ram heavy duty trucks - assembled in Mexico and have the associated build quality problems more often than they should.

Also the standard Ram 6-speed that comes with the non-HO is not really built for loads like you're pulling, and the Aisin requires a silly amount of maintenance and also has reliability issues more than it should.

I hate to say this, but I'd consider going with the new powerstroke if I was in your shoes. I'm a GM guy, but they've not figured out the programming on the 2020+ transmissions and way too many folks are having problems with them. If you want to get a pre-2020 Duramax, they're pretty darn bulletproof, especially the 2017+ with the L5P motor like my 2019 model. But I think in the HD lineup, the Ford may be the best for heavy loads right now. The inline Cummins will always be the best motor, but the transmission and the rest of the truck around it are enough to turn me off. My last two trucks before this duramax were Ram half tons and I loved them and had very few problems, but they were made in America and not the same as the HD lineup at all. I drove a couple Ram HD trucks in my shopping research and I didn't care for them at all.

Wait until they package the Allison with the Cummins - it's coming.

And the HO has no additional displacement - it's just tuning.

But they still have crappy front ends for some reason.

I know there has been talk of an allison behind the cummins, but I also know they have a ZF transmission they are looking at. I think either would be fine and an upgrade to what they currently use. I really like the 8-speed zf in my half ton, the larger version for the hd's i believe would be similar. With all the negatives you hear about on the 10-speed GM/Ford transmissions wonder if RAM would stick with the ZF 8-speed setup just to avoid the headache.

I believe i read some time ago the new RAM transmission was to be debuted in the 2022 year model.

My dad has a 2018 HO cummins 3500 srw (aisin trans) nothing but good to say about it.

Im a sucker for the inline motor, GM and Ford dont have a chance for me in the HD diesel category.
