Don't know much about the 6.4.I have the 5.7 in a 2013 1500.According to the specs,not much difference.If I remember right,just 15 more horses and 25 ft lbs. of torque.My 5.7 pulls like a champ.On RVNETI saw a thread about the 6.4.Not much help to you.

Both motors are great and gas hogs. I would be more interested in the Ram's new coil rear suspension than anything.

I have a 2014 CC short box XL FX4 with the 6.2 and 4.30 rear end. Love it. We just upgraded to a 2015 crusader 360BHS and it pulls it just fine. 70 mph and it gets 8mpg. 60-65 and it gets 9.0 - 9.5 (hand calculated). Now I special ordered my truck back in October with the 4.30. I wouldn't change a thing.

We went from a 9600 lb Cougar to the 12600 Crusader three weeks ago and just returned from a 1800 mile trip. Truck did fine, although I did install Firestone air springs last night in the garage. The crusader really made the rear end sag.

Now I will say I have owned two other f250's ( 7.3 and a 6.4 power stroke). Yes the diesel was better in hills as they would not downshift as much, but off the line I feel no difference when towing. The 6.2 with the 4.30 read end gets out in traffic the same way as the diesels with 3.73.

Hope this helps.

We have a 2014 Ram 2500 Heavy Duty with the 5.7 Hemi. We pull a Chapparal 267RLS and get 12.6MPG. Empty we average about 16.2 MPG.
The 6.4 Hemi is not worth the extra and the MPG is less than the 5.7.

Not necessarily true. I had a 5.7 and just upgraded to the 6.4. While I don't know how long it would take to pay for the cost difference in gas, so far I get a few mph better with the 6.4. I have not towed much yet so time will tell if that holds up.

What's your thoughts on the coil spring rear on your new 2500? Did you get the airbag upgrade?

I test drove several 2500s as well as a few 3500 srw. Keep in mind this is also my daily driver so that had a lot of bearing on my choices. I tow a relatively light hybrid camper so I really didn't need the 3500 but the difference between the leaf springs and the coil were quite noticeable. The coil springs give a great ride for a heavy duty truck. I like the ride better than the 1500 I was driving. Feels more solid. I drove one with the factory air bags and liked it fine, it just did not have the options I was looking for. The rear end of the truck with the factory air bags was about 3" lower than the trucks without. Not sure if that is normal or not.

We bought a 2014 Ram 2500 with the 5.7 a few months ago when we traded our Grey Wolf 28BH for a 2014 Wildwood 27RLSS and I am very pleased with the performance and mpg. Just returned from a trip from North Texas to Southfork Colorado and averaged 9.3 mpg traveling at 62 mph. Topped Raton Pass at 55 mph and never touched the brakes all the way down the other side, gearing down the 6 speed automatic held the speed to an even 50 mph. Truck performed flawlessly and never seemed to labor over any of the passes or long uphill pulls. Initially considered the 6.4 but opted for the 5.7 primarily because the 6.4 is in it's first production run. Our first hemi was in a 1500 and it did a great job with a lighter trailer but the 2500 with the new coil spring suspension is by far a superior tow vehicle with plenty of excess capacity if we elect to upgrade our trailer in the future.

2014 2500 HD 6.4 here. Upgraded from 2008 5.7 mega cab. I get better gas milage with the 6.4 and pulls a heck of a lot with ease. Very happy with 6.4. I bought off the lot and it came with 20 inch tires. It looks like a beast

I have the 6.4 l hemi in my 2500. I get 17 around town. Towing is 10 mpg. The rear suspensions is great while towing. I have no complaints at all. This truck gets better gas Milage than my old 5.7 half ton and my 2012 CTD. Very happy so far and no shortage of power. I didn't notice the gas mileage improvement u til I turned 10000 miles. Once that happened it got a lot better. I have 2 of these trucks, I own. Landscaping business. Both 6.4 L and both have about the same performance.

You're getting 12.6 pulling with a 5.7 gas? I'd keep that one, you've got better numbers than the diesels.

I assume your loaded camper weight is around 7500lbs...most gas trucks with that weight are getting 9-10mpgs on a good day...12.6 MPG's with your 5.7?...is that hand calculated?
