Topic: 2017 Ram 3500 6.4L dually. Should I?

Posted By: Wagonqueen Truckster on 01/22/17 07:23am

Yesterday day I drove a new 2017 Ram 6.4 Hemi Dually. I know absolutely ZERO about dodge products. In the past 20 years I have owned all Ford trucks and Chevy SUVs. Currently I carry my old camper with a 99 Ford 350 with the Triton V 10. Although it has under 100,000 miles, the years of hauling heavy loads for work and the general bad weather of PA, is showing her age. A heavy duty truck is integral to our business. Hauling six thousand pound sometimes.

Although I have no plans on getting rid of the Ford, Dodge has some pretty good incentives right now and this particular dually came up on my truck watch. It's hard to find duallys on dealer lots. Anyways, can anyone shed some light on this truck. You know... power, engine, payload, opinions, experience?

I drove a '15 Chevy 3500 with the 6.0 back to back with a '15 RAM with the 6.4 engine 2 years ago. I was really impressed with the 6.4. It felt a lot stronger and a lot quicker than the Chevy 6.0. My boss ended up getting the Chevy instead for financial reasons and it's been a good truck. But, if I were picking a new HD truck with a gas engine I think the RAM 6.4 would be the one to get. Particularly since you can get that engine with the Aisin transmission which adds PTO capability along with MD toughness.

The 6.4 gas engine is considered by Ram to be a medium duty truck gas engine, has 429 foot pounds of torque and 410 hp. Payloads for the dually can be upwards of 6-7000 pounds depending on options. I don't think you can go wrong with the 6.4 if you want a gas engine. In comparison the high output diesel puts out 900 foot pounds of torque when mated with the Aisin transmission.

Think it would sufficient for a 3000 lb TC with a dually stable lift?


Posted By: towpro on 01/22/17 11:33am

wagonqueen,
you can go to the RAM body builders website pick your year and truck (17 is probably very close to 16 weights) than on left side you will see "camper guide" click on that. go down until you find your truck listed. (be sure to pick 3500, 2 or 4wd, match cab, bed length, engine, GVWR and seats. no field for SRW or dually, but that is already in GVWR field as SRW is less) I noticed they had a mistake and showed both 6.4 and 6.7 as diesel (3500's are 1/2 way down).

once you find your truck it will show you center of gravity info for truck campers. as well as "remaining cargo"

back on the main index screen, you can also click on the page that shows Base Weights/GCW/Payload/Trailer Tow

I have a 2016 ram 2500 6.4 and the power is unbelievable. I couldn't justify $10k+ for the diesel and I'm really happy with it. After 2400 miles however my average mpg is 12.7 but I can buy a lot of gas before I could buy a diesel.

Ram 6.4 with camper Review TC Magazine



I found the review by TCM to be a little disappointing. Nobody purchases a gas engine for the fuel mileage. It just won't happen when towing or hauling heavy. And the magazine chose not to opt for the 4.10 axles that give both a better chance for the cylinder deactivation to work and adds 1000 pounds to the GVWR, thus increasing available payload that is something the magazine is almost anal about never exceeding. I seriously doubt the 4.10 axles would give any less gas mileage and maybe even better mileage when towing or hauling. Yesteryear the 4.10 axles would yield less fuel mileage than 3.73s but with todays transmissions it is not that big a difference, if any.

Exactely what I wanted to read.


Posted By: Bedlam on 01/22/17 06:41pm

I would have chosen the Ford 6.8 V10 over the Ram 6.4 V8, but the 6.4 over the Ford 6.2 V8. The V10 is only available in Ford's chassis cabs in a detuned version, but still impresses me for a gasser.

See my sig for my setup though it's SRW. Even with the 3.73, it tows the 2,400# camper with 2,800# boat in tow in 6th gear at 62mph. Drop down to 58 mph in 5th and I lose about 1 mpg which is about the same as you would lose with the 4.10s running loaded. Drop down to 55 mph in 5th and get about the same as 62 in 6th.

I choose the 3.73s figuring I would be in 5th with the camper on board, but actually find if I run 64mph on the interstate, the truck loves 6th gear and doesn't seem bogged down.

My father has the 6.7 diesel in his DRW version of my truck and it seems to be getting about the same mileage regardless whether he is towing a 15,000# FW or his 5,000# TC.

The only thing I miss is the exhaust brake, but I've never come close to overheating the brakes even coming down long steep twisting bake roads off the BRP.

My last Dodge truck was a 2004 CTD which I sold with 180k miles after basically trouble free miles.

In regards to the warranty, I think the warranty on the gas engine dropped to 60,000 miles.

Thanks all. I appreciate all the input. Making the decision by tomorrow. I think I am leaning towards the purchase. My Ford is fast approaching 20 years old. We have a 2014 Chevy Tahoe we are trading in. With trade in value minus what I owe, plus the factory incentive and dealer deals, I am looking at this Ram at $32,000 out the door.

If you want to get some good baseline prices on the truck you want check the websites for Dennis Dillion and Dave Smith. Then you can go to your local dealer and negotiate.

Always good to get an idea of costs, but hard to compare apples to apples when one has a trade in.

I respectfully disagree with this statement. According to the 2016 RAM 2500/3500 brochure "The 5.7 HEMI V8 and the 6.4 liter HEMI V8 are mated to the long-proven 66RFE 6-speed automatic ". I don't believe that the AISIN trans is available with the gas engines in the 2500/3500 trucks but that combo may be available on the 4500/5500 gas engined trucks.
I believe that the OP is referring to test driving the 3500 series dually.

Never could or will buy a Dodge. [emoticon]

I know that doesn't help one bit. LOL

If I was going to buy a new truck today I would sit in and drive all 3 and then I would buy the one that's the most comfortable for me to sit in and drive.

How much difference does a few horse power of a few hundred pound cargo weight really make anyway??

When I bought my Chevy that's what I did. Never compared the specs until after I bought it.

The Chevy had the least hp (20 less than Ford and can't remember how many less than the Dodge), it got the best gas mileage, has heaviest payload and a highest resale value and was and it is hands down ergonomically the best to me out of the three.

In just over 3 1/2 years I've put over 100,000 miles on it and replace 3 light bulbs. Other than maint that's it.

I've been a die hard Ford man my entire life but I do love this Chevy PU. [emoticon]

I agree.
using online ramtrucks.com site, I was able to outfit the 3500 with 6.4HD gas engine, and 4:10 gears, in both SRW and Dually, but the only trans choice is the 66RFE. any other trans forces the diesel engine option.

there are a lot of these 6.4's out there, all using the 66RFE trans. there should be a track record that can be viewed on the internet sites.


Posted By: kohldad on 01/23/17 10:03am

The only problem with the 66RFE is the larger than normal gap between 1st and 2nd. It is absolutely no issue getting going, but is large enough that you have to stay in 2nd gear longer than one would like when manually downshifting.

The 6.4 in certain situations when engine braking adjust the valve timing to provide additional engine braking. When it engages, it is very noticeable. Just wish the Ram engineers took advantage of this feature more agressively as it is a great benefit.


Posted By: Wills6.4 Hemi on 01/23/17 10:46am

I just bought a new 2016 CC DRW LB 4x4 with the 6.4 Hemi, I love it and should have bought it sooner IMHO. Mine has a payload of 5,973 LBS. It tows very well!!!


Posted By: Kayteg1 on 01/23/17 11:14am

I went via some research last year and build my Ford truck last December.
It went into production last week and should make it to CA in about 3 weeks.
I know buying from the lot has some thrill, but even there is good number of duallies in 1 hr driving radius, I could not find the truck I like.
I want RWD Supercab with electric heat, 360' trailer cameras (those look very impressive on site).
Deleting opitions I don't want kept the truck price low and most of the dealers would sell the truck to me for invoice price, what is about 4 grands below MSRP.
The normal Ford's incentives still apply.
I am not married to Ford, but finding Dodge dually with long bed was huge hassle as well.






Posted By: Bedlam on 01/23/17 12:12pm

About 15 years ago, I decided I was no longer going to settle when buying a new vehicle or RV. I have been ordering what I want if I cannot find it built and have been much happier. Over 10 years ago, I found I could deal with fleet/commercial for my vehicle purchases and am even happier interacting with dealers. I've always been after the best value for me, so seeing something discounted that does not "fit" me does not get me excited. Give me a fair price for exactly what I want and don't waste our time with games - Now that's something to get excited about.


Posted By: towpro on 01/23/17 01:23pm

I already know how to look up invoice and dealer costs, etc and have always dealt with the truck fleet salesman. the truck I bought in 06, after working my best deal, I ended up getting a chance to get it through the friends and family program (someone I met on internet worked at factory and gave me of his several per year he was allowed to use.) It was only like $200 better than the deal I had already worked out, but 2 bills is 2 bills.

This time with my 2015, I had checked the sites and already knew the deal I expected.
As I was standing in dealers lot looking at the truck, I tried www.truecar.com. internet sales person called me while I was still standing there, the price she offered beat my expectations. I took it home the next day.

MSRP $58,150, out the door for around $42K with tax. but it was late July when new trucks are about to hit the lots.

That was a GREAT deal. Wow.

I did buy the Ram last night. I wanted a gasser. Around here, the 3500 is hard to find in a gasser already on the lot. MSRP was $ 48, got it for $39, but they gave me a great trade on my 2014 Tahoe, on which my kids racked up the mileage to 74,000 in only 3 years. High miles on a 3 year old car. Needless to say, now that I have the new truck they have been assigned the 99 Ford for the remainder of their driving years here in this household.

Hahahaha. The 2 in question are 16 and 17, but the 4 other children, who are now either married or in college, played in part the destruction of many many Vans, SUVs and a Trucks. And when you have a family of eight, BIG vehicles are the norm. They all learned to drive and test in either a Suburban 2500 or a V 10 truck. Girls and Boys. Actually the girls can parallel pArk a dually in downtown Pittsburgh without batting an eyelash. Although one of them did total out my favorite truck. My Ford 350 Triton V 10 short bed. I miss that one. LOL.

That's awesome. I am pretty sure my camper is around 3200. With vintage (76 Amerigo) it's always difficult to say exactely how much they weigh without taking them in for an actual reading. Back in the day, they advertised them as 2700 lbs, but that seems way under reality for such a huge camper.

I disagree, I have Two Ram 3500's one is 13 Mega Cab and the 16 Long bed. The 16 gives much better mileage due to the gearing.

This is a little sparce in information. What are the axle ratios, engine type, tire size, weight of trucks, transmissions, and what were you towing/hauling to come to the conclusions you have asserted?

My comment was/is related to the 6.4 engine with cylinder deactivation and otherwise the same year and same exact truck except for the difference between 3.73 and 4.10 axle ratios. It appears you are comparing differing years, differing trucks, and possibly driving the diesel engine that I was not referring to.

Again, same exact truck. One is long bed with 3.73 gears and the other is Mega cab with 4.10 gears. 3.73 gets better mpg when driving.

My comment stands as this is a thread about the 6.4 engine and so was/is the TCM magazine article. The specific issue is cylinder deactivation. The diesels (that you have) do not utilize cylinder deactivation under light loads. With the 6.4 and 4.10 axles the cylinder deactivation can occur more often than with the 3.73 axles under a load tending to lessen any gas mileage difference between the two axles.

JMTANDEM is correct. This thread is about RAM 6.4 HEMI gas/3500 dually trucks not diesels or other brands. I would like to see comments from owners or others that have driven these particular trucks. Even though I consider myself a GM guy I am interested in the RAM 6.4 gas dually.
