The thing I liked best about my Duramax was that it came bolted to an Allison.

So I have had good luck with a 6.4 but I just used it as a truck to tow cars with and didn't pretend it was a race car as diesel idiots tend to do.  If given the choice I would probably go Cummins tho.  My thought process is diesel engines are supposed to be a straight 6, if they were supposed to be any other configuration tractor trailers and industrial applications would use them but they stick with the straight 6....gotta be a reason for that.

They do have an advantage in a pickup truck for ease of access.  This is clear.  But the idea that this configuration is somehow "better" is something I don't agree with nearly as easily.  They win in US trucks due to more liberal length constraints.  This was not always the case in this country and all the manufacturers (esp Mack) built legendary V8's.  And currently in Europe, V8 is still king- again it's about length.  And guess what?  These Euro V8's are making A LOT more power than US spec I6's.  I'm guessing because they can squeeze more cubic inches into them.

Thanks for all the input!

The Cummins commands such a huge premium over the Ford or GM.  I don't mind spending the money if it's the right thing to do. Just wasn't sure how much of the extra cost is fact versus fanboi

Some things, like divorce, good whiskey, and big TVs, cost money because they are worth it.

Doesn't the 6.7 Cummins also use the CP4 pump, at least in some years?  If so, that concern applies there instead of just to the Ford 6.7. 

Depending on how many miles you plan to put on the truck and therefore how much fuel economy matters, you can always find a gas truck.  The 2005 - 2010 Fords had the 3V 6.8 V10 as an option and those make pretty good power (as much or more than the diesels of those years, the 6.8 just has to rev higher when you need the power).

It's common knowledge that the 6.4 (MaxxForce in IH parlance) is a turd.  But if you can make it stay together, and a few have, that engine will best all challengers in the power wars.  All of them.  It can make  REDONKULOUS power.  Look at the rods it uses.  It makes even the 6.7 PS rods look puny by comparison.

But I'd avoid it unless I was a sled puller or drag racer.

All the power in the world doesn't matter if you have a crappy transmission.

 

I'd rather have a 4.6 with the accelerator permanently bolted to the firewall if it meant the transmission wasn't a ticking time bomb.

5R110 found behind the 6.4 (and 6.0) is one of the best in the business.

You mean the shopped around v8 Cummins nobody wanted?

I haven't heard anything but it's clearly made to exist at stock power levels and that's it. It's a redux ram imo.

It's really bad.  Some people here had first hand knowledge of the design and build and did not recommend, and just read the car and driver long term test of one, it was really bad.

No specific quality issues, but I'd spend my money elsewhere. They didn't make many of them in the first place, the compound turbo is unique to that application, and buried in an oven between the heads but below the intake manifold. If you have an issue, you get to take it to a Nissan dealer who may or may not have ever seen one, because it's the only modern diesel Nissan has ever sold.

I'd go with an HD gasser if you're always towing 7-13k and shopping in the sub $20k range. If you want something a little more livable and you're not always towing, the right 1500 gas truck could meet your needs too.

No Nissan, copy that. The primary mission of the truck is going to be towing between 9,000 and 10,000 pounds.  I'm sure we will use it for some household duties, but it won't be a daily driver. I will start looking at the gassers.

V10s are real nice for what they are, we have one in an F650 and an F450 before that and both did just fine for its intended purposes which is local haul, not over the rockies, sitting for a week some times.  

V10s drink the fuel but non-deleted modern diesels do to and care and feeding of the modern diesels is a real mess unless you wanna start getting into deletes and then they are borderline unregisterable depending on where you live and how much you like lieing to the government.

V10s also got the 5R110 trans so thats a win.

GMT800 Silverado 2500HD with the 8.1 and the Allison.  You could actually get that combination in the Avalanche too, although it was pretty rare.

The Avalanches all have the 4L85E like the Suburbans. Every Avalanche 2500 is an 8.1 which is nice though. 

I love my 8.1 burb, so of course I have some bias. 

Inline 6 diesels make a lot of sense for service, packaging, and parts counts (one head, one cam, simple block machining, etc). It's also much easier to plumb a single turbo, and they have some benevical natural balance characteristics. 

I work at Cummins. There are no Cummins-powered Titans in the lot when I go into the office, if that tells you anything.

A 2017 truck will have DEF, a 2000s truck will not.

I don't know if the Fords have it, but one of my favorite RAM Cummins features is the Auto exhaust brake.  Turn it on, head downhill, let off the gas, and the exhaust brake will hold that speed all the way down.  Zero braking needed for my 24' car trailer on the CA Grapevine.  Mine is a '21 so I don't know when it became a feature.

Another good option is 2011+ Ford F-250/F-350 with the 6.2 gas engine. This will probably be what I buy if something ever happens to my 2015 Ram 3500. 

GMT800 with the 8.1 is another good option. I had a 2500 Suburban with the 8.1 and I loved it. Only sold it because I needed a truck to pull a 5th wheel camper.

2010 Cummins didn't use DEF, I'm quite happy about that :) I think the integrated exhaust brake might have been introduced with the 2010 as well, I know mine has it.

My current Uhaul is the 8.1 and Allison.  It's great.  I think the challenge with the GMT800 is they are aging out.  Finding a well cared for one that I can rely on is getting harder.

I've been looking at 6.2 trucks. The engine is a tank but the "super duty hop" is my concern.

We have been phasing out our fleet of 6.2 F250s and F350s, after 200k loaded with a service body (no trailering) they are pretty much used up.  Moved on to Dodge's with the 6.4s and the guys like them a lot better.  Only thing they don't like is the trucks are physically smaller/narrower so the service bodies are smaller, at least the ones we are putting on the trucks are.

The Superduty Hop is a real thing!  Scares the crap out of you when it happens.

they did for a short stretch, 2019 to 2020 if I remember correctly. There's also a recall to replace them with a CP3 pump, I think parts availability has been scarce but a buddy just had his done a month or 2 ago on his 2019, so they might be getting more parts in or it was just finally his turn in line.
