I submit it should be engineers but suspect it is a battle between the legal department and marketing department. From BoatUS:

"No, You Go First…

A move by the Society of Automotive Engineers (SAE) to simplify the confusing tow vehicle specifications has become complicated. The idea is to provide the tow vehicle buyer with a guide, beginning in 2013, for comparing one tow vehicle's capacity to pull a boat and trailer with other tow vehicles using the same standards. For the past five years, truck manufacturers met to find common ground on how to provide a real, rather than hyped, towing capability for both cars and trucks. Operating under the name SAE J2807, consumers would use these new standards to see actual towing capacity for every vehicle.
Ford says it's applied it to their all-new vehicles but adds, not all of the 2013 vehicles are in that category. General Motors says it won't release their specs until Ford releases theirs. Chrysler, builder of Dodge Ram trucks, says it won't, either. Nissan is only making the standards available for the 2013 Pathfinder because that vehicle is all-new and future vehicles will be rated in subsequent years. Honda vehicles with a tow capacity of more than 3,500 pounds are using the standard now while Toyota has been offering J2807 since 2012. So, an industry-wide towing measurement, agreed to by everyone, isn't happening. Besides, each manufacturer says the idea is voluntary. The real reason? Nobody wants to "telegraph to the competition," as one tow vehicle maker admitted, what their vehicles can do. Some J2807 figures have shown a drop of 200-300 pounds in towing capacity for specific vehicles.
Jack Pokrzywa, SAE Manager of Ground Vehicle Standards, tells BoatUS, "We do know from our experience that standards level the playing field and we hope that the value of this standard will bring all the parties together over time.""

Well, That clears it up. :huh:

If you are asking what it means, it says there is NO agreed, engineering based, protocol for determining tow rating for trucks for consumer comparison. It is all just a number the manufacturer decides to publish. One brand may have been blamed, in the past, for the failings of tires, made by another company, on it's trucks and may feel the risk of bad publicity may warrant a highly conservative tow rating. While another may want to look tough on paper and assign a higher number to a lesser truck.

How is the end user to know what the real tow rating is???

At the present time tow rating by the manufactures are meaningless. Until they all use the same standard there is no way to compare trucks. SAE J2807 is a big step in the right direction but most won't use it on their current trucks because it will show how much they have overrated the towing capacity in the past. Toyota is the only one who has published numbers based on the SAE J2807 ratings.
I have a friend who has a 2004 F150 that is "rated" to tow 9500 lbs. What a joke. He tows a boat and trailer that combined weights around 6000lbs and has constant overheating problems with both the engine and transmission when ever he is on a long hill. On a hill near here he struggles to maintain 70 Km/hr. With my previous truck that was rated to tow 6500 lbs I could maintain 80 on the same hill with a heavier load. My present truck is rated to tow 9,800 lbs using SAE J2807 and I can tow my 260DA on a trailer without seeing the transmission temperature or engine temperature gauge even move from normal. On the test hill I can easiely accelerate going up the hill and had to back off the trottle because of traffic at 110 Km/hr.

Yea, I got it.

Interesting point. So they may join sometime in the future after they have time to "adjust" the truck and numbers to meet real world.

I think as they bring out new models and improvements they will test to the standard but will not go back and restate numbers for present models. Hard for any manufacturer to come out and say we rated this truck for xxxxx lbs towing but when we test to real life standards it will only do this much which is alot less than we said it would do.
Toyota actually did reduce their ratings on existing trucks by about 400 to 500 lbs based on the new standard. So far the big 3 have refused to do this. I mean come on do you really think the F150 with the eco boost engine will tow 11,300 lbs, it sure hasn't lived up to its hype as far as fuel economy is concerned.
 
My V10 Excursion does a great job with the 270DA & steel trailer......about 11,000lbs. A bit over my rating I believe but never has overheated or strained pulling the hills of PA, Mike.
 
Is it possible the "s t r e c h e d" truth is in the heavily advertised 150 or 1500 class and not so much in the workhorse trucks?

Without a uniform std in the past I don't see that any manufacturer has to be guilty of 'stretching'. Here are a couple links that will give a better idea of SAE J2807. I can see a simple reason for couple hundred lb adjustments for example.

mike; what ever you can hang on the back and keep the front on the ground:huh::smt021
 
Each manufacturer determines their own rating.

Perfect world I would take 3 and make it one. The Tundra Crew Cab Body, with the Dodge Cummins engine and the Allison transmission in the GM's.
