Going to get a new Ram Have a 2012 3500 Dually going to go to a 3500 crew cab 8 ft bed SRW, is the HO worth the 3 thousand upgrade over the standard cummins. I have the high output on my dually but torque is 800 # so is it worth it or not. Also have a 4:10 rear end on existing but thinking 3.73 on new one would like a little better mileage when not towing. Have loved the dually for pulling our 36 ft TT but going to go to a fifth wheel and not anything huge usually just me and wife with grandkids visiting some times. SRW will make daily driving a little easier.

The truck you want to buy is nearly identical to my 2014 crew cab, long bed 2500. My Cummins is 370HP/800TQ with the 68RFE transmission. I pulled a 14,000lbs 5er through the Rockies just fine and never felt overmatched by the trailer. I've also pulled gooseneck trailers in the 15,000lbs range and it handled that very well. The OEM engine brake is out of this world for towing [emoticon]

Is the HO upgrade worth it? The extra 275 ft-lbs of torque is nice and the Aisin transmission is more stout than the 68RFE. Is it $3K better, I'm not sure because the standard 385HP/850TQ is a pretty good package. Also, I don't know if you can get the HO package in the SRW 3500.

Absolute #1 thing for sure: Get the factory 5th wheel and goose neck prep packages! It's only something like a $500 option and worth it's weight in gold. This setup makes install and removal of the 5th wheel hitch a breeze. Plus your in-bed wiring is already done as well.

The optional camera package is really nice. I've driven the newer trucks that have the bed view camera and it makes lining up your 5er pin really easy. Obviously you can do this without the camera, but man it makes things so simple and eliminates those 2 or 3 trips in and out of the cab to check alignment.

One final suggestion. If you get a 4X4, order the OEM side steps. These trucks set really tall and unless you have some long legs it's a real stretch up into the cab without the side steps. My truck had aftermarket steps when I bought it and I had to replace them. I went with OEM and they are so much firmer and solid feeling than the aftermarket ones.

The SRW crew cab long bed truck is definitely narrower than the dually, but it's still a land yacht. Easier to drive for sure than the dually, but you still need to plan your turns and watch your mirrors because these dudes are looooooong

That's a good question. Even the standard engine has big power. I'd say you definitely don't NEED it but sure would be nice.

The HO option also gets you the AISIN tranny. It's more robust than the standard 68RFE. Whether that matters is up to you.

Ram switched back to using the CP3 pump in their 2021 SO (standard output) engines (used the CP4 from 2019-2020). Chevy quit using the CP4 a few years ago. Ford still uses the CP4.

Not sure if Ram went back to the CP3 for the HO. Definitely something you might want to check if you're leaning towards the HO.

If you're not familar with the CP4 backstory suggest you google it. There's a number of class-action lawsuits involving Ford's CP4. Given a choice, I'd definitely go with a CP3 vs. a CP4, even if it meant giving up some HP/torque.

Well a new 2021 Ram 3500 SRW LB will have a 12,300# GVWR, the same as your 2012 has. Going from a TT to a 5er, how big are you looking for a fiver, pin weight on anything over about 15,000# will put you at or near that GVWR.

HO/Aisin most of the upgrade cost is the Aisin, love the way our tows and shifts. Eight years of driving a DRW I would stick with DRW and the 14,000# GVWR that comes with it.

Personally, I would ABSOLUTELY go for the HO engine.

As far as CP3 vs CP4, I'd wait to get a true confirmation on that before allowing that to weigh in on the decision.

For what it is worth, the CP3 on my 2012 did fail. And while a failure there isn't as expensive as a CP4, I would say they both can happen, and both are rare. Sure wouldn't make a difference on a decision to buy if I were in your shoes.....

The big difference between a CP3 and CP4 failure is the damage that results to the fuel system with the CP4. With the CP3, replace the pump and carry on; not quite so simple with the CP4....

I used to feel the CP4 situation was a little overblown . . . until Ram made the switch from CP4 "back" to the original CP3 a month or so ago on the 2021 SO engines. This switch speaks volumes about the lack of confidence Ram had in the CP4.

I think the pump failures are rare and at least Cummins seems to look after you if it happens under warranty. The CP3 is a much more reliable pump than the CP4. It is capable of handling a bit of abuse and if it does fail it doesn’t destroy the rest of the fuel system. That said I wouldn’t base my decision of what truck to buy solely on avoiding a crappy designed CP4 pump. The regular output Cummins has higher compression pistons in it and is likely to get a little better fuel economy than the high output.
