Is that paying someone to do it, or do it yourself?
I get a shop to do it.
10mpg empty?? Are you pretty heavy footed lol?
Not particularly. My truck is also a Power Wagon, so it's got the big rubber and it is 2" higher than a standard 2500. Most 6.4L guys on the Ram forums are getting 10-12mpg.
I believe on 3/4 and up MDS is not available. So you're feeding all 8 cylinders all the time.
Hell my Daytona ram w 5.7 hemi and MDS only bested 15mpg downhill with the wind at my back , and I never towed with it.
Mine has MDS. I find no difference in economy when it runs. I've run tanks of fuel through the truck with the MDS defeated and got the same hand calculated mileage.

Have to watch the year of the hemi, my brother has a 2010 I believe (not sure if it's the 6.4) only had 50k miles on it motor didn't last a few months before replacing cam, that lasted only a few months before the whole thing blew. Replacement was from a newer truck and ok so far. Tows around 15k once in awhile and you know it's there but it gets it done. It's a 3500 CC though, so different then the pickup versions. If you're towing really rarely, it might be ok, but regular towing i'd stick with a diesel. Having say that, it's the only gasser he owns and regrets it 100%. It eats fuel like no tomorrow it costs more to run then the diesels, and the cost of the engine was a lot.

As far as extra $10k for a diesel, look at the used prices of trucks, you will get that back at resale, maybe more. 2500/3500 hemis here are worthless no one wants a gas in a heavy pickup. Some companies went to gas because it's cheaper if they abuse them like not warming up, etc. For someone with their own truck it's a lot different.

So I have a 201 5.7 hemi in a 2500 with 181k on the clock that I have driven since less than 100 miles. For a hauling truck and running around I'm happy with it. For towing, eh, the mileage is pretty awful. I am however considering a new 3500 with a 6.4 and that new 8 speed transmission. The price is one of the biggest factors and the fact that I don't run the truck everyday anymore. It's basically my at home work vehicle since I have a beater for a commuter.

I’ve always wondered why so many people are hung up on the extra purchase price of the diesel when the resale value pretty much zeros that out.
Fuel economy from the gas to the diesel can be huge if you make a lot of miles especially comparing a 5.9 Cummins to a gas 6.4 or 5.7.

I've got a '15 2500 Power Wagon w/ a 6.4. The only thing that stops it is gas stations. I can keep it in the high 15s on the highway, but stop & go takes it down to 14 and change. Towing anything significant will drive it down to 10-12ish.

When I buy it will be new as I want the 8 speed trans, and used truck pricing is flat stupid. I do not tow all the time, just occasionally. I do not care about resale value as this will most likely be my last pickup until i retire or awfully close to it no more miles than i put on my trucks. I am perfectly fine with 15ish highway and 10ish towing as that is about all my 5.9 Cummins gets. Best I have ever seen from it, empty, highway, hand calculated is 16.75mpg. I have tried tuners, I have tried exhaust, has always been well maintained, recent injectors, it gets no better. As I have said in my past posts, I have owned my 5.9 Cummins for 10 years, I am well aware of the costs of owning a diesel not to mention the added cost up front. I want to know what guys towing experiences are with the 6.4 hemi. Thanks.

You guys arguing maintanence costs, take a look at your locations. You are comparing Canadian to US costs for items. We (Canadians) have a significantly higher parts and oil cost vs our U.S. counterparts for the exact same product.

Well I have been on and off the fence regarding buying a new truck for the last couple years, and I have been back and forth between gas and diesel. I am finally off the fence. Ordered a 2021 crew cab 3500 Laramie with the 6.4 Hemi on Saturday. With the added 12k up front, plus the issues Ram/Cummins is experiencing with the CP4 high pressure fuel pump grenading and wiping out the whole fuel system in the process (injectors and all), I just couldn't pull the trigger on another diesel. Max I pull is 14k a few times a year (and typically not very far), the rest of my towing is around 7k and less. Should be here in 2 to 5 months.

I think you will be blissfully happy with that gasser. If I were buying new it would be a hemi, for what heavy towing I might do I bought a pre-DEF 6.7 CC with the six speed manual. We rented a 2018 1500 with the small hemi and 8 speed auto for a road trip last summer, what an amazing truck! Drove like a dream, comfortbale, crazy power when you needed it, and after putting about 2,000 miles on it all over Oregon, Idaho, and Montana, we still clocked an overall MPG just a shade above 20! Mind you we weren't towing, but western terrain and 80mph highway speeds once we left Oregon made her work hard for her oats.

Enjoy!

Thank you! I hope I am blissfully happy lol, this is my first ever brand new vehicle and probably my last truck as I have a company vehicle I drive during the week, unless something with that changes I won't put enough miles on the new truck over the next 19 years to wear it out.

The hemi isn't bad if you don't need a diesel, just hope nothing changes and you keep it forever, you will not be happy with the resale value if you decide to sell in say 3-5 years. 2500/3500 hemis used are worth nothing. And considering a laramie hemi is about the same price as a slt Cummins that would always be worth like $10k more used, it would hurt.

Well the company I work my day job for had all diesel pickups in the past now only f450 and up are diesel. The guys all want diesels but in 4 or 5 years times the trucks get 200000 or so miles on them (the ones on the front line) by that time they are totally trashed not worth it for a diesel IMHO. The 6.2 Ford powered f350 i drive normally weighs 10000 ish had 15000 ish hooked to it and it drug it up the Pennsylvania mountains and got the job done if it where doing it daily it would die but on occasion it is fine. Just the truck out and about runs plenty good enough get 10.2mpg and its Normally held on the floor with a lead foot. I've personally owned a 7.3 f250 a 6.7 f350 and not a 3.5 ecoboost f150 and I will say the f150 is my favor it does great donuts in the fields and forest tows great and will get 18 or 19 mpg the 7.3 got 15 and the 6.7 got 13.2 didn't matter up hill down hill or towing the hill. And once the trailer gets over 5 ton I just take a real truck

One CP4 pump failure outside of warranty and you have just negated the resale differences, and hurts even worse when I don't have 10 to 15 grand in my wallet to fix it when it goes down.

True dat!

The resale thing doesn't pencil, if you only get back what you paid up front it's still a loss. You probably paid interest on it for the life of a loan, and then it was tied up until you cashed it out, which is a zero sum game. No, if you need or want the diesel, then get it, but if it's not a necessity (or in my case pure devotion) then I believe you're money ahead to get the gasser.

Exactly, no vehicle is an investment. They are all an expense, period.

It's hard to blame the truck when people are abusing the hell out of them. That is the reason many companies went to gas pickups because they are cheaper, and will take being abused better in many ways then a diesel. For someone who looks after the truck and tows/hauls a decent amount, the diesel is far better. JMO but if someone told me they were "normally held on the floor with a lead foot" when driving my truck, they'd be looking for a new job. That equipment provides for your paycheck, you should be looking after it. Too many people forget that.

They are few and far between. Some will have the problem sure. You also need to remember what % of owners are online posting about issues, and how many of the people with problems helped caused them. But some gas engines will only make 100k-120k before replacement. Unless you are incredibly unlucky or don't look after it the diesel will last at least 250k before needing much if anything and that's still very low compared to how long most of them go. Even with a $10k repair, that diesel will be a lower operating cost when you factor in purchase, interest, maintenance, fuel, and resale compared to a hemi if you are towing/hauling regularly. Heck empty the diesel will get way better mileage.

You're looking at it wrong. Let's say that diesel is $80k new, hemi is $70k. When you go to sell them in a few years that diesel will be worth $50k and that gas will be worth maybe $30k. As long as the diesel resale value is above $20k it will fetch far more then the extra amount it cost new. No one wants a used 2500/3500 gas truck. You cannot give them away. A used few year old diesel? Most dealers can't keep them on the lot and if in good shape command a massive premium.
