I currently own a 2004.5 Dodge Ram 3500 5.9 Diesel and I'm in the market for a truck. My Arctic Fox is a nice trailer but it's a beast (12K+ lbs). My truck is bone stock and has 325hp and 600lb-ft of torque. I would say it is sufficient but on the edge of its abilities to pull a trailer of this weight.

Of course, I'm looking at diesel versions of the big 3. But the Ford 7.3 with its lack of DEF and turbo complications make it very appealing. It has 430hp and 475lb-ft. I would be considering the F350 version with 4.30 gearing to get the most out of it for towing.

Does anyone have experience yet with this TV towing something similar to mine?

Any thoughts on how this might compare with the towing experience I'm having with my truck?

12k is well within the capabilities of most of the gas engines.

I would disagree on the turbo if you do much towing in the mountains a turbo is a big advantage (the gas engines should do it fine just have to wind up the RPM to compensate)

DEF is a non issue, lower fuel mileage and range would be my concerns with a gas engine.

Agreed, turbos are nice for power but add complexity. They may be rare, but I have a buddy who was stranded for a week in Flagstaff, AZ because of DEF issues with a Silverado Duramax. I'm likely to end up with another RAM diesel. But, there's something so appealing about seeing a pushrod V8 sitting under the hood and actually being able to see the ground underneath.

In the TFL towing tests, the 7.3 got 2.2mpg going up the Ike. The diesels didn't do much better (all were towing 16K lbs). But they used the computer calculated mileage so take those numbers with a grain of salt. The big advantage to the diesels was in the downhill run. Far less touches of the brakes in the diesel trucks.

What kind of fuel economy are you getting with your Ram ? I'll bet a new equivalent model would be worse !

I don't know about the rest of the US, but in my little corner, gas is about $2.19. Diesel is about $2.49

As for power, with a 4:30 rear axle, the 2020 Ford Towing Guide says 15,000 lbs MINIMUM, more depending how you hitch up.

Interesting. Diesel are not know for good engine braking !

We had a 2001 8.1 gas engine and 3500 2wd dually. We have a 2005 3500 2wd duramax and have driven on I-84 many time with both trucks. Going down the cabbage hill for 6 miles in Oregon there was no difference in being under control towing the same fifth. chevman

That's why they all come with excellent exhaust brakes or other now.
My 2016 RAM CTD shown in my signature was a delight to run in the mountains - both up and down.
My old 2002 Ford Power Stroke 7.3 not so much, but it ran like a top for well over 300,000 mile when I finally traded it.

Yeah, 12K is well within the 6.4 Hemi capabilities, especially with the 4.10 gears. For that load I'd be looking pretty hard at going gas (Ford, Ram or Chevy/GMC). The new tranny offerings in HD gassers has really helped narrow the gas v. diesel debate. Or, more accurately, has raised the load considered to be comfortably towable with a gasser. 10 years ago it seems 10K was most people's limit. It seems to be creeping up almost to 15K with some of these new engine/tranny combos.
