The addition of the Exhaust Brake was a major factor for me upgrading from my 2005 Duramax to a 2011 Duramax. In approx 30K miles the 2005 need new brake pads, while the 2011 was still on the EOM pads when traded with 115K on the clock.

All the comparisons are the 7.3 gasser vs. anything but a modern diesel with an exhaust brake.
Compare a 7.3 gasser to the same year diesel that is the relevant equation.
All the other comparisons are antiquated.

^^^There is absolutely no disputing the fact that the modern HD diesels can hold back much better than a 7.3 gasser on a hill. But the 7.3 has adequate engine braking for lighter trailers. A person wanting a gasser to pull his 15k fiver shouldn't fear he's going to wear out his brakes towing in the mountains without an exhaust brake.

You are a brave lad !!! Can't argue the fact of what a 7.3 gasser will ,or will not do , but I towed a fairly heavy fifth wheel many years with a 7.3 Powerstroke , no EB . Had a few white knuckle experiences coming of some of the hills in Utah, Idaho ,and Montana . Yes learned pretty quickly on how to come down some of those long grades . One example is the one coming from Ennis,MT to Virginia City , MT. It has the runaway ramp if needed .
The ability to rev to 6000 rpm; work against a closed throttle plate; and the torque multiplication of the 4.615:1 low gear ratio all work together to give the Godzilla a massive advantage over a 7.3 diesel when it comes to holding a trailer back on a long steep grade.

well if 2016 isn't new enough, our 2016 with EB on FULL, and trans in Tow Haul, pulling about 13,500# going down a steep hill 7%+ it will slow well below starting speed. It will actually down shift and keep slowing!
Now history, our 2001 Ram 2500 CTD with NV4500 (5 speed manual) with a PacBrake EB, I could reduce speed as much as not more being pushed by the same trailer. Street driving I could almost bring it to a stop without touching the brakes.

The bottom line might be that where a Cummins comfortably holds a 15000 lb trailer back at 55 mph the Godzilla might hold that same trailer back in low gear revved to 6000 rpm going 30 mph. Beyond about an 8% grade you’d probably have to use some brake applications or shift the transfer case to low range and go slower than 30 mph with a gasser.

Yes, this is the comparison I want to make. Yes, I out hear about how great exhaust brake works. Side by each, diesel with and without, easy to show that it works. And they can write ads, every body on the net swears need diesel because of exhaust brake.
But can you show me where a modern 7 Liter diesel is compared to 7 Liter gas, like gears and loads, holding back on a hill? How about 5 liter? 3 liter?
I highly suspect a lot of this, because manufactures have not shown such a test, is pushed to make people spend the extra for the diesel

You are a brave lad !!! Can't argue the fact of what a 7.3 gasser will ,or will not do , but I towed a fairly heavy fifth wheel many years with a 7.3 Powerstroke , no EB .

One example is the one coming from Ennis,MT to Virginia City , MT. It has the runaway ramp if needed .
I have no doubt 7.3 gasser will hold back much more than 7.3 diesel with no engine brake. My question is will the Powerstroke, with exhaust brake added, slow any better than the 7.3 gasser.
I have no idea . I entertained the thought of EB ,injectors etc. on my old 7.3 diesel , but decided to just go with a new truck . I drove that old Powerstroke for nearly 16 years , great truck ,just didn't get it done towing a heavy fifth wheel .

There's no comparison of the 7.3 Gas with a throttle body, and transmission grade braking compared to a 7.3PSD that has absolutely no grade braking functions.
Bottom line...I'll take a 7.3 Gas over a 7.3PSD anyday for all towing applications.
I will take a 6.7 Cummins over both of them for all tow applications .
