Default 6.4 Hemi questions.

Anyone got a RAM 2500 or 3500 with the 6.4 Hemi ?
How do you like it? 6 or 8 speed automatic transmission?
I don't tow but I do have a slide in truck camper.
Any comparisons to Ford 6.2. Or comparisons to 5.7 Hemi ?

I have a 2016 2500. Just under 50k miles, very happy with it.

edit - 6 speed tranny

Iím your huckleberry. Lol. 2019 Ram 3500 4x4 with 6.4, 8 speed, and 3.73 rear. Camper is Northstar 8.5 Arrow. Have not scaled it but Iíd guess itís around 3200 pounds wet. Previous truck was a 14 Ram 2500 with 5.7. The 6.4 with the 8 speed transmission is an enormous upgrade. Much less high rpm running while loaded and my fuel economy is about the same. What else would you like to know?

Yes you are! I also have a 8.5' camper!
What kind of MPG do you get with the camper on? We usually stay off the major highways and go about 60-65 MPH .
You are happy with the 3.73 rear end? I'm up in the air about what gears to get. It won't be a daily driver.
Thanks!

Very happy with the 3.73 rear. Truck is not a daily driver for us either. We did a 3600 mile road trip in February from Mass. to Key West with the camper and kayak/bike trailer. I kept the speed around 65-68 with tow/haul mode engaged. Some use of cruise control when the traffic was light as well. Overall average for the trip was 11.5 mpg.

I canít understate what a huge improvement the new 8 speed transmission is. It is really a game changer.

Good info, thanks for the replies!
I can live with those numbers, much better than my old 6.0 Chevy.

Had a 2500 5.7 6 speed. Just bout new 2500 6.4 8 speed. Love it. Lot more low end power and mpg is a little better if not going over 75. I think itís a good combination.

Hey Bob. Another thing I forgot to add. You should do your best to find a 3500 over a 2500. The leaf spring suspension of the 3500 is much better suited for truck camper applications. The 2500 coil spring suspension requires a lot of upgrade to limit side to side movements. The price increase of a 3500 over a 2500 is negligible and youíll be much more satisfied with the ride

Do you have to use midgrade fuel with that engine?

Here is what is printed in the owners manual regarding octane rating. I have compared 89 to 87 to see if there was a noticeable increase in mpg or performance. In my unscientific comparison, I was not able to tell any difference

I have a 2018 and love it. Tows my boat/trailer around 10k lbs no problem. Gas mileage blows and 1st gear when trying to get a heavy load going isnt the best. Daily driving is very comfortable though and better than I expected coming from a 1500. One thing that annoys me is the TPS which cant be turned off so you have to run rear tires at 80psi or the check engine light comes on. Once I am due for new tires I will most likely change out shocks to Bilsteins for a little smoother ride

Had I been able to wait another year I would opt for the new transmission which I have heard shifts smother and gives better MPG.

That's the only question I thought of later was how stable it felt with the camper on, and if you
added anything to help. I did not know the difference between 2500 and 3500's , good to know!
What brand of tie down system did you go with?

I have a 2019 2500 Big Horn 4x4 with the 6.4 and I believe the 8 speed transmission. The truck is a beast, tows like a champ.

I rented a 2500 with the 6.4 and 8-spd trans for 2 weeks, while my Ford 6.2 was in the shop. I noticed a marked difference between the two engines. The 6.4 felt like it had more power and I got about 14 mpg empty, compared to the 12 I get in my Ford. The Dodge had 4.10 gears and my truck has 4.30's.

Iíve used the same tie downs and suspension modifications on my last 3 trucks and done the installations at home.
Torklift tie downs: rears are pretty simple but the fronts not so much. One part of the front bracket mounts to the spring bolt, I believe itís a 33mm socket with a torque of 300 ft/lbs. Broke the snout off of a 24 inch breaker bar. Also, one of the other bolts was a pain in the ass.
In the rear suspension I use Timbrens and Rancho 9000xl adjustable shocks. Both are easy to install, reasonably priced, and work as advertised.

I had 24 years in the automobile and truck business, and consider myself a "car guy."

But if I was going to look for such a vehicle today to handle such a heavy camper, my pick would be the F350 dually with the 7.3 gas engine.

The 7.3 engine has finally arrived and information on the internet points to it being a far superior engine to any gas motor on the retail market. GM also has a new 6.6 liter gas engine that's a modernized 6.0, and the 7.3 tows circles around it too. Five Star Tuning has already got a tuner designed for it, and it improves power and driveability over OEM.

A dually is overkill for an 8.5í camper, itís going to kill your fuel economy, and necessitate swing out jacks.
On a 9.5í to 11í camper I would certainly give the Ford a hard look, especially in an F450 configuration.
The 6.6 GM is hamstrung by the old 6 speed transmission.

I donít buy something without extensive research. That extensive research made me confident that the one ton, srw, gas powered Ram is the most reliable and the best value of the presently available hd trucks

Andy, did your camper require bed spacers with the Ram ?
I was reading on a RV forum that guys with new Fords had to raise the floor of the bed and sometimes space the front to keep the camper back a little .
Thanks,
Bob
