Regardless how them 2 TFL jokers do their “tests” there is ZERO chance that ANY gasser pickup has anywhere near the holding power of a comparable diesel with a good exhaust brake. Not even worth discussing. Not even if you’re trying to blow the pistons out backwards at 6000rpms in 3rd gear, “grade braking.”
Again, anywhere from Denver to Appalachia/Canada to Mexico, a gasser will serve just fine. Not many kill ya hills in fly over states.

Well... this thread imploded quicker than I thought. Not a single soul is saying that a gas engine brake is anywhere as strong as a diesel exhaust brake.
I'm just trying to get real world users to give their experience. But typical RV.net, it goes sideways immediately.
Appreciate the consistency guys. I'll just try different forums and hope that people can read and stay on point...

Umm in your first post, you asked how the engine braking was compared to your Cummins diesel.
I’m totally on topic, btw. Just because I respond in a colorful manner, no need to get the ole bvds in a twist. The Ford 7.3 brakes as well as any other naturally aspirated gasser of similar displacement with a locking torque converter. It doesn’t do “better” or “worse” than any of them. IE there’s no magic built into them. If you’ve never used downshifting a gasser to provide compression braking before, and only towed with your 2015 Ram, you will be seriously disappointed once you see how much brake dust is on your wheels after coming down a pass with a heavy trailer hooked to any gasser.
Other attributes? All the gasser HDs have comparable 8-10 speeds and work similarly and well. Ford has more displacement and a few more ponies.
Only real downside is the significantly reduced peripheral visibility driving a Ford, with that paper bag you have to wear over your head, so your buddies don’t know it’s you….![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/biggrin.gif "biggrin")

Good luck, if you try hard enough someone will support your flawed hope that a big gas engine will hold back a heavy load going down steep mountain passes. I am not a fan of Ford's method of using the service and trailer brakes to hold back a load without many knowing that the truck could overheat it's brakes and the trailers brakes
without the operator being aware of it.

the Allison on our 2001 3500dually with the 8.1 liter did a great job of holding speed towing down mountains with our 35 ft alpenlite that was a combined weight of 22900 lbs. but engines and trailers need to be matched for best results. The 05 Duramax and the 2001 8.1 worked the same going down the cabbage patch on 84. retired rv'r chevman

I have a 2023 F350 Crew Cab short box with the 7.3 and 3.73 rear end. I tow a 11000-12000 lb 5th wheel and love it. When running on flat ground I can just leave it in 10th gear and it'll run 70 MPH all day long. Hilly terrain I just lock out 9-10 and it'll cruise at 70 in 8th gear at about 2100 RPM with no problem. I get about 9 mpg towing but it tows it effortlessly. Haven't gone to the mtns or anything yet so I can't reference engine braking but plan to next summer. I'd given some thought to the 4.30 rear end but with what I'm towing I don't feel it would be any improvement.

Who's worried about a typical steepest it can be 6% interstate grade?!?!? Not me. Be it a gaz or deezal!
There are some 15% grades in the NE corner of Yellowstone....that can be interesting.
Otherwise, I haven't had but one rig that would not hold me on a downhill. That was my 88 SW K3500 where the POS th400 lost the ability to shift to 2nd gear. So you went 60-70 mph down typical 4-6% interstate grades, or 25-30 no brakes in 1st. It would hold 15k lbs in 2nd before loosing that gear. My 89 R3500 did that too.
For what it's worth, my 14 4.3 V6 is every bit as good or better pulling my equipment trailer at 6500 as those to supposed mountain climbing 454's were.
As Grit points out, as long as your on a typical freeway grade, the new rigs be them gaz or deezal, will be fine.

It's always the same issue on a clear sunny day in light traffic everything is always fine.
But on a rainy, windy, day in heavy traffic or whenever conditions are not ideal having the optimum equipment makes a difference.
Pretending a gaz engine descends the mountain as well as a diesel is
misleading.

The 2005 Duramax did not have a factory exhaust brake.
Compare that 05 Duramax or that 8.1 to a a modern diesel with a OEM exhaust brake and you will find there is a significant difference in slowing power going down the grade.

NO it is a dangerous statement, as some novice might think I am good to go.
I wonder Blt2ski has even owned a diesel with an exhaust brake. I know he has towed around the NW with older equipment.
