You driving one of those now huh? Looking at all of the half ton's out there...I don't think I can really go wrong anyway. My burb only had 290hp new but 410ft/lbs of torque. All of these new motors seem to be at 383hp or more and 400ft/lbs.

Same if not more wheelbase and more gears in the tranny means it should be a smoother pull as well.

Lastly...with the 454 I get 7.5mpg towing and 9mpg around town...

My wife has a 15 ram 5,7, speed, 3.21's . The max tow rating is 7k with 3.21's, 10k with 3.73's. My wife's truck gets good mpg (16/21), but not sure I would want to tow 7k with it. It rides great and is pretty quick. I had a 3500 with 5.7 and 4.10's, with 9k-10k toy hauler it was a 6mpg dog. 7k on flat's it would have been ok but not in the rockies. If you get he 1500 ram, I would get the 3.73's and plan on sway bars for a 7k trailer. The hemi likes to pull hills at 4k-5k rpm, takes a bit to get used to.

I just picked up a 18 ram 2500 diesel, winter driving with studs and in 4x4 50% I'm getting 14-15. Hoping for 12mpg with the trailer when the snow melts. But I'm mostly towing around NW MT.

I need to buy a truck very soon to replace my 1999 454 burb. There are a lot of nice 1500 5.7l trucks out there for sale. I have been looking at the following 2012 - 2017's:

6.2l ford
6.4l hemi
5.7l hemi

My rig will mostly be a daily and tow 7k once a month. There will be some planned multi-state trips this year.
I should be but I dont use the trailer brakes with this set up and it did just fine. I have had a few dodges and like them the best.

I have had an f150 work truck and I absolutely hated it.

Yup 5.7. Been up over Snoqualmie over to Crashes to run Reiter and back over Stevens, and been down central OR with it a bunch so up out of Biggs and couple other nasty steep hills coming back...

What trans is bolted up to these 6.4L trucks?

6.4L is only a power wagon and a 2500/3500 motor right?

You sure about this? Tried to tell my buddy about this and he said it did not work

He is averaging 7.8-8.5 in his 6.4L PW , unloaded

Stock, or larger tires? That seems pretty bad. Hell, thatís Chevy 6.0 range.

I will have to try turning off the MDS on my truck. Havenít ever messed with it.

Works on my '16 PW. I'm running 37's and am getting like 10/14 unloaded indicated on the computer. Computer lines up with hand calculated =/- 0.5mpg. That's with a speedo that is uncorrected for tire size, so it's probably actually a little better. I don't drive it very hard.

My understanding is that there is no way to untraceably turn the MDS off permanently. So if you have a warranty, you are going to have to buy a second ECM to swap in when you take it in for anything. It's not like a GM MDS system where you can just get an OBD dongle to turn off the MDS, then remove the dongle to set everything back exactly how it was.

I think you get the 68RFE. 6 speed auto that seems pretty good in the short time I've had it. I don't know if you can get an Aisin in a 3500/6.4 combo.

Whoops. I did some reading on them just now. Seems that they are similar but different

16 PW on Toyo RTs 37x12.5 and corrected with AEV ProCal here. 11-12 unloaded here. Mostly city or going above southwest interstate speeds. 8-9 with either a single rig or small camper so far. Regearing to 5.13s in the near future now that I've got a little DD.

66RFE which is some combo of 65 and 68 architecture from other reading.

How do you like the AEV ProCal? It looks like I need one of those for my re-cal and a Range Technology disablement tool when (if) they come out.

It does what it's advertised to do. I tweaked the speedo a few times the first day and haven't touched it since. It's too bad the TPMS requires a dealer visit (or full scan tool) BCM reset.

I'm hearing that AlfaOBD is the way to go now though. More functionality than the ProCal which is just dipswitch uploads.

I actually just reset my TMPS threshold on my 2015 a week or so ago with AlfaOBD. No more orange light on constantly, plus the EVIC display stays on wherever I left it now instead of going back to the tire pressure screen every time I start it. I haven't messed with the speedo yet, but it sounds pretty easy to do.

Android only is a bit of a drag. Search led me to RamForum. There's actually some decent tech there and a good bit of traffic.

I first looked at getting the windows version (since we didn't have any Android devices), but ended up getting a $50 Fire 7 tablet to run it. I haven't used it a lot, but so far so good. As a bonus, I can use it to stream music in the garage instead of having to use my phone.

What year did the 6.4L first appear in the 2500/3500 trucks?

looking into that, the tire warning bullshit is annoying. I run my winter studs at 45psi unless I'm hauling.

Apparently theyíve made it harder for 2018+ models. Iím sure someone will come up with a solution eventually. Going to keep watching it as I like running mine around 65 if not towing.

You can still do it with alfaobd, you just need a bypass harness due to the security. Look at the thread on ram forum or Cummins forum, it's all there.

You can get a 6.2L V8 in some F150 trucks and GMC/Chevy offers their 6.2L V8 in the Silverado/Sierra 1500s........but only one V8 is available in the Ram 1500?!

What's the power specs of the current 5.7L Hemi?
