6.4 Hemi 2500

Who's got a '14+ Dodge with the 6.4L? Thinking of selling my 04.5 Cummins and going to a new gasser. I don't pull heavy enough, often enough to justify the $9k buy in on the Cummins and honestly all the new emissions shit scares me on them with some stories I have read. Anyone gone from a 325/610 Cummins to a newer big block Hemi and regretted it? Towing duty would be my bumper pull toy hauler that weighs around 11k fully loaded once a month or so.

We have a bunch of them at work. They seem adequate, but it's a gov't fleet that never leaves a 50 mile circle of flat land. A buddy of mine had a new one last year and got rid of it due to oil consumption. It would smoke on start-up after sitting for an hour or so after driving. It used too much oil between changes for his comfort. A couple of our work trucks will blow a blue cloud on start-up like his did, though I don't know how much oil they're actually using. I don't think this is anything new with vehicles that have MDS though, my brother says his Honda uses oil too. None of our 5.7s do this, and my wifes manual trans Challenger 5.7 uses zero oil between changes. I don't like the idea of new vehicles using oil in this day and age, seems like BS to me. The 6.4s do haul ass empty though.

How many empty miles do you plan on putting on it? It seems that's where the fuel expense favors a diesel truck.
If I were shopping new, or almost new, I'd be looking at had trucks myself. Ford 6.2s seem to have the edge tho

A friend of mine had a Cummins Megacab but got rid of it since the wife didn't like the 6 speed and he went to a Power Wagon with the 6.4L to tow his camper. I towed the camper with that truck once for him to take it to get some work done to the camper and while it had plenty of power, it kind of grated on my nerves pulling hills with the V8 screaming the whole time. Recently my friend went back to a Cummins with the automatic and seems to be happy with that.

That is one of the most annoying things about towing with a gasser. My 3V V10 is loud at 4000 rpm.

Most miles will be either empty or pulling my 12' trailer with the RZR on it. I only tow the camper every couple of months. For the $9k less for the gas motor over the Cummins I can buy a lot of gas. Plus gas is $.50-.60 a gallon cheaper than diesel where I live and almost always is so the improved mileage from the diesel is probably negligible when you factor in the increased cost of #2 over gas.

I like mine. 14 -15 mpg empty, no oil consumption. (My Chevy got about 12 and burned a quart of oil every 3k miles.)

Good power empty, tows my 2nd gen on the heavy trailer good enough (12klb or better) and tows my 5klb camper easily.

4.10s and 35"s.

If I was towing a big fifth wheel or two place car hauler all the time, I would go diesel, but for normal use it's cool.

I have a 16 3500 Ccsb 4x4 with almost 60k. I am extremely happy with it. I do haul equipment often-around 14k load-here in NH so hills,highways and backroads often. Only bitches I have are I hate the mirrors and the only reason my next truck will be a diesel is for the engine brake.

I've been pretty happy with mine. I average 13-14 mpg with about 28000 miles on it. Towing it is generally in the 7-10 mpg range. It definitely doesn't have the low end power that my diesel did though. The only problem I've had with it is the transmission shift solenoids going out and putting it into limp mode. Ram has since came out with new solenoids and I haven't had any problems out of them.

Talked to a buddy yesterday that has a '15 CCSB Cummins with 6 speed auto that is wanting to upgrade to a new truck. Gonna buy his for trade in value.

I have driven it before and it's a nice truck. With only 40k on the clock it should last me another 12+ years like my 04 has.

Sounds like a win. Aisen, 68RFE or G56?

They are really nice/solid trucks. I think you will be very pleased. 50k miles on mine.

he wasn't sure but from my research the 2500 Cummins in '15 was only offered in the G56 and 68RFE? I thought the Aisin was offered too but maybe that was only in the 3500?

Yes sir. I believe the Aisen was only an option in 3500s. You will be happy with the 68. They work well.

I bought a '16 with ~17,000 on it on Halloween. I've put about 5k on it since then. Averages 12 mpg, mostly around town. It'll do 15-16 mpg on a 55 mph highway. It will haul ass empty, and doesn't slow down much with 5k behind it. Can't say on heavier loads because they go behind a bigger truck.

My only real complaint is the variable displacement. It comes in and out at inopportune times and makes the truck feel like it shifts too much. Also, at certain load/RPM combos it's pretty loud in the cab.

I went with the Laramie with leather, and it's very comfortable and nice to drive. But as of now, my plan is to pay it off in 2 years and go back to diesel. Find one just out of warranty and delete it.

You can turn off the MDS. Simply select "6" with the +/- shifters. This also shows the gear you are in. I always drive like this as the MDS was annoying. It doesn't hurt/impact anything else except the variable displacement from engaging...

Just watch the GVW on the Power Wagon. It's only about 8500lbs where a normal 2500 is 10k lbs. Quite a loss of payload with the Power Wagon package.

I was looking at the Power Wagons thinking 3/4 ton Rubicon til I saw the reduced load capacity. There are several on Autotrader in my area with pretty low miles too. Does the mileage suck that bad that people buy them, don't drive them much, then trade them in?

I dunno. I love mine.

12-14 mpg on 37s with stock suspension
Lead trail runs a plenty and have trailered home rigs that broke following me
IMO, handles a single rig on a open trailer great

Love my Power Wagon... GVWR Nazis won't buy thm, but I can tell you, everything is the same as a regular 2500 except tires, wheels, and rear springs.... Wheels are stout (Alcoa designed) tires are 17" 3195 lb load rating. Springs are a bit softer/taller than 2500s.

Stock, mine handled the 1500 lb TW of my trailer no issue. I have added airbags/daystars as I plan to run some additional weight (after first checking there are no bus loads of nuns on the road.)

Ramv, just in comparison, how does the suspension handle compared to the avalanche?
