I would be leery of the small form factor diesels given the above. I don't keep up with that market segment, but it doesn't look good.

It isn’t a question of whether smaller diesels will be discontinued, just a question of when.

Stellantis owns RAM and VM Motori who makes the Ecodiesel. Stellantis is under investigation in Europe for multiple counts of consumer fraud relating to diesel emissions. At some point they will decide it is all just too much trouble and cut their losses, IMO.

GM has announced the end of selling all gasoline engines in light vehicles by 2035. Light diesels would logically stop production sooner than that.

The smaller diesels were largely developed for other markets, and modified to meet US standards. As Europe shuts down light diesels, manufacturers will lose the volume that sustains their production.

I have a v6 Mercedes diesel in my Jeep Grand Cherokee and it’ll pull my 27’ Overlander anywhere I ask it to. What I like is that as a daily driver, I’m not forking out enough fuel to run 3 cars when I’m not towing.

But the dealer suggested we look at the 3.0 diesel and comparing performance, it's not bad. HP is lower of course, 277 vs. 420 for the 6.2L gas. But torque is exactly the same, and at much lower rpm. The other attraction is the new Escalade takes premium gas, and that has become very pricey, comparable to diesel and sometimes higher. Certainly 3.0L is not comparable to the 6 liter Duramax diesel, but that's not available in a SUV and we really don't want to move to a pickup. So my question pertains to the 3.0 liter Duramax only, nothing else. I would love to hear from anyone with real life experience with this engine. Thank you.

I have The Ford F-150 with the power stroke diesel and it’s tows my 25rb International just fine the only thing I wish it had was the exhaust brake like the GM has.

When Jeep-Chrysler -Fiat-Stellantus was doing advance production testing on the upcoming $100K Grand Wagoneer, they built two so-called test mules with beefed up frame, axles and suspension and dropped in the 6.7 Cummins diesel from the Ram pickup. It appears they are holding off on offering this powertrain at least initially and plan on using 5.7 and 6.4L gas V8’s to get the GW going again. The fact that the test mules exist shows that Jeep is at least considering a full-size luxury SUV with real diesel towing abilities.

They built the new Grand Waggoner on the 1500 chassis, not the 2500/3500. It doesn’t offer a diesel (neither does the Grand Cherokee) but if it did it would be the Ecodiesel.

For OP
The 4 people who actually tow AS with their Duramax 3.0 diesel said;

No problem pulling, averaged 16 mpg on 10 day trip.

Great tow vehicle.

Great engine & economy towed 27’ 4000 miles since February no issues.

It’s smooth economical and fun. No issues. Would make the same decision today.

I tow new dry AS from plant to dealerships & back and utilize a WDH & CAT scales. Seldom do I have to tow 30/33 Classics. I tow with the 3.0 Ram Ecodiesel as it’s very efficient to 65. Recently turned 800k miles albeit not on the original engine. I suspect the little 3.0 Duramax in-line diesel would meet OPs towing needs well plus very efficiently and likely with good maintenance great durability.
