Does anyone drive one or have experience with it?  I am looking at upgrading to 3/4 ton but don't feel like I "need" a diesel.

We pull a 4 horse gooseneck and average 7 - 8 mph. It pulls fine, but we are in florida on flat ground. The motor is a bit louder than the chevy we pulled with.

I decided to get a gasoline engine. There dealership found just what I wanted. It has the 6,4 Hemi. I love it. I have never had any problems with it. I got the Lonestar edition (Big Horn). I will say that you probably need to put the mid grade gas in it. I get anywhere from 16 to 19 miles per gallon just running around and about 12 pulling my trailer. One horse or three horses, doesn't matter. Mine is four wheel drive. You never know when you will need that!   That does lower your gas mileage. Trailer is 3 horse gooseneck with 4 foot short wall. 

Currently I drive a 2018 4x4 ram with the 5.4 hemi and love love love this truck and I am impressed with the hemi's performance.  It has really surprised me.  I'm pulling a steel 2 horse slant with front tack.  but - kids...... my husband says I should put a gooseneck with extender in this truck, but I am leary leary leary about goosenecks and 1/2 tons.  Trailer is an aluminum 3 horse slant - no living quarters, just the front tack and it is light enough to be under the trucks tow rating - but it still worries me. 

This was exactly my experience with a 6.4 in my last truck. Also a 3/4 ton 4x4. Lots of power and reasonable milage. I have a new Ford F250 diesel that really does not do any better on fuel milage than the 6.4 did. I would own another Hemi 6.4 truck, and may do that again next time around.

The 6.4 is a perfectly capable power plant if you are a weekend, casual hauler. 



Word of caution, get a little taller gear than you would ordinarly think you would need and it will help with the trailer. 

This is exactly why I am looking at the 6.4 hemi vs diesel - I do not haul often (few times a month) or for long - maybe 30-40 miles one way.  Lots of stuff close by that doesn't require long trips.

I like this information!!  It makes me feel like I am going in the right direction.  Thank you!!

With the price of diesel fuel normally being higher.  The cost of going down the road is not always favoring the diesel engine.  It would not suprise me that the big 3 will come out with big cubic inch twin turbo gas engines at some point.  I like my diesels but with the cost of upkeep it looks more likely the next truck I get will be a gas.

Just do a comparison of the cost of your daily maintanace items of the two.

Oil changes

Fuel filter changes

Air filter changes.

My husband has a duramax - and my daddy was a diehard cummins man - I am aware of the maintenance cost of diesels LOL, it's crazy. - another reason I'm looking at the 6.4.  It will also be my daily driver - but i have only a 20 mile commute to work.  I also do not want to HAVE to deal with DEF system if I don't have to.  We had the duramax deleted as soon as the warranty expired.

you mean like the 7.3 liter Ford new for 2020? 

It's like you have crysal ball 

6.4 Hemi is great. We have two. One is a 3500, the other is a 2500. Neighbor has one also and he loves it. No regrets. Lots of power. 

One reason I buy a diesel is Longevity!!! Yes upkeep is more , and slightly higher fuel costs. BUT....... with a gas rig your going to need to replace it LONG before a diesel. You don't see many 200-400,000 miles gasoline engines on the road. Diesels easily do those numbers.  Another thing is STOPPInG power. I pull a 15k pound LQ and like my exhaust brake. I don't believe gas engines have those. 

I hope Chrysler LLC does not hear about this. 

The diesel most certainly has a place in the LD truck world. It's bad ass, and it's pretty much all my fleet runs. 

But for a great portion of the recreational barrel racers out there it's over kill. The 6.4 is capable, it's trustworthy and it's affordable. For a not a lot of $$ you can also buy an unlimited milage Power train warranty and you are seeing mroe and more Hot shot guys going to the hemi and a large majority of the Oil Field Service guys are also. 

I happen to know of a dozen or so 6.4 that are well on their way to being 300k + engines. 

and if you need an exhaust brake to stop a 15k trailer you need to learn to drive more betta 

I am driving a gas engine right now- 2008 GMC 2500 with 325,000 miles on it. Drives like it did when I bought and pulls better now. BUT I change the oil every 5,000 miles and try to not ever get below a 1/4 tank before I fuel up with Shell gas. I don't haul every weekend, but my daughter had it in Colorado and she lives in western Colorado in the Ridgeway/Ouray area. It was her everyday driver making calls all through the area. If you treat you your gas engine right and don't haul a lot they will last you a wile. All our gas trucks have had at least 250,000 miles before we sold them. Even then, they were still ok. We had one that lasted for over 500,000 before it cratered.
