OK. So why does a vehicle equipped with the 6.7 PSD have so much more GCWR than an identical vehicle equipped with a 7.3L gas V8?
Same frame, transmission, brakes, wheels, tires, axle capacity, etc. What is different in the vehicles other than power output of the engine?
What makes the PSD safer than the gasser?
or is this GCWR just advertiseing about who can pee the furthest?
I am not going to pretend to know, but I could speculate. I do know you need to abide by it though, per Ford.

Well, here it is. The manufacturers agreed to a standardized tow rating because or all the bullchit they had spread in their advertising in past years. Check out SAE J2807 standard tow test.
In the end, it is still advertising and no more.

Thanks, I’ll check that out. I heard it’s a BS test. My only point was to tell the OP how to make sure he abides by Ford’s guidelines to calculate max trailer weight. They are squirrely, so I did my best to make it straight forward and by the book. Could he use the other method with axel and tires weights and stay physically safe? I don’t know, probably. I just didn’t want to give him anything that wasn’t by the book.

Lol, I thought the video was going to discuss the details of the SAE tow rating test.
It figures that a law was probably created to regulate tow ratings, because some company was lying, someone believed it, went off a mountain, and lawsuits followed.

Well, AFAIK, SAE J2807 not a law; but a standardized test that the manufacturers agreed to.
That is surprising. Nothing gives me warm and fuzzies like the fox guarding the hen house. Old Chevy could legally say they could tow 187 tons or whatever it was in that commercial. It’s up to consumers to know they need to dig into the fine print to see if those results were obtained using SAE J2807.
That article is from 2015. The J2807 was revised in 2016 and then again in 2020. However, I don't know what the revisions were. The details on the SAE website are behind a paywall.
For the braking requirement, is the truck required to stop the trailer on just the truck brakes, or is it truck and trailer brakes combined? I haven't found the answer to that but I suspect it's truck only since the parking brake requirement is truck only (obviously).

Yes, from 2015; but that article is the most comprehensive explanation I have found to date.
And as far as the braking requirement, IDK. That is why I like Wyoming’s requirement, vehicle combination must be able to stop in 40’ or less from 25 MPH. Regardless of trailer weight, number of axles with brakes, number of trailers, or whatever. Pretty straight forward.

Watch the video close and one can see the frame of the old chibby bending!!!
Another issue is that the SAE, like all engineering societies, is comprised of members of the automotive industry. There is no separation of powers so to speak. It’s essentially the automotive industry creating standards to test itself against. Obviously, it would be in all of their interests to devise tests that create numbers as large as possible, even if they don’t translate into real world results.

Yes, that is true. However, it is a “standardized” test which the manufacturers have agreed to. With that being said, it is somewhat biased toward light duty trucks. (Class 3 and lower). In the “start, stop on a 12% grade”, I am sure that a new F450 would do that in less time than my last class 8 Kenworth with a C15 Cat set at 625 HP with a 40,000 pound trailer behind it, just due to the fact that the KW would be more cumbersome and an 18 speed transmission isn’t going to be as quick as the auto in the Ford. Yet which one would tow more?

Totally agree. The tests don’t really seem that rigorous. For example, going up an 11.5 mi pass doesn’t really seem like it does anything to prove the vehicle can tow the load long haul. You’re back to trusting the manufacturers on that. I agree you need a standardized test, but what probably happens is the manufacturers put a lot of effort into passing the test with best in class numbers, and then time and budget is cut from other testing that might be more important to us.

Oh trust me, on that particular 11.5 mile grade, it can be brutal. It get HOT there. It is not unusual to see regular vehicles, not towing, overheat on that hill. I live just a few miles from it! There are folks that will leave multiple gallon jugs of water in various places from about half way on up to the crest. They get used often. That hill WILL find any weak points in any cooling system.

Ok FRAGO, the further I delve into this rabbit hole, the more I realize that I don't know ish about ish lol. So now we're looking at a smaller TT to do some serious traveling in to learn about RVing before we bite the bullet and upgrade to something full-time. I appreciate everyone's input, and great advice!
