. . . reading the Ford 2017 towing guide it clearly states not to exceed GVWR or RAWR. So that 8200lb F250 with a GVWR of 10000 is limited by a 1800 payload which limits what tongue weight it can handle that limits the weight of the trailer. That big rear differential and axles are wasted weight that can't be used to they're potential according to the ratings. This truely shows how screwed up the HD truck market is right now

The Platinum Reserve XD does indeed have a lower payload than my SV and yes you need more truck than the Nissan because you follow the numbers. But that doesn't apply to the Ford F-250 diesel, it's got a special engineered spec that says you can double the payload and still be okay.
The HD market is far from screwed up. I assure you, no "special engineering spec" is required. Quite the opposite.
I'm sorry, demiles, but you give me the impression you do not understand what's behind the "artificial" 10,000 lb. GVWR used on the Big 3, 3/4-ton trucks. Hey, not to worry. I was in your shoes about a year ago. It took some digging and a bit of head-scratchin' to finally comprehend the issue.
I realize you've been comparing the XD specs with the Ford 250. FWIW, the specs and capabilities for all the Big 3 trucks are very similar. They have to be in order to be competitive. I'm much more familar with Ram's specs and capabilities, so I've taken the liberty of using Ram trucks to make my point.
First off, don't you find it odd that nearly every late model, Big 3, 3/4-ton truck has a GVWR of 10,000 lbs. or less? Ever wondered why? Is it because the Big 3 lack the technology to make a 3/4-ton truck with more than a 10,000 lb. GVWR? Highly doubt that--lol!
A GVWR of 10,001 lbs. and higher requires special licensing and registration in some situations. The 10,000 lb. and under GVWR fills a "legal" need in terms of less stringent licensing and registration. The current 10,000 lb. GVWR, 3/4-ton truck was born to meet this consumer need by slightly derating the rear suspension of a 1-ton SRW truck. Why did they do this? Because the Big 3 were able to R&D two complete lines of truck for basically the price of one---a win-win for the manufacturer and consumer. If the Big 3 could have gotten away with it, I'm sure they would have preferred to have only changed the badging (vs. the badging and the rear suspension).
In any case, the ONLY difference between a 3/4-ton diesel and 1-ton SRW diesel (at least for Ram), is the rear suspension itself, and the chrome 2500/3500 badging stuck to the door. Ninety-eight (98) percent of the frame design, 100 percent of the differential's internals, the 8-bolt (full-floating) axles, hubs, bearings, tires, engine, tranny, front suspension, brakes,---the entire drivetrain are EXACTLY the same on each line of equivalently optioned truck. A quick part numbers check can quickly substantiate this.
I mentioned this in my previous posts, but hopefully it'll make more sense now. By looking at the RAWR rating for the 3/4-ton and the 1-ton SRW Ram trucks, it's obvious the 3/4-ton truck's rear suspension was only derated 500 lbs. (vs. the 1-ton SRW). Why do I say this? Because the 3/4-ton truck has a 6,500 lb. RAWR (with 18-20" wheels) vs. the 1-ton SRW's, 7,000 lbs. RAWR. The FAWR is the same for both trucks, 6,000 lbs. And to further make my point, the tow capacity for the 3/4-ton and 1-ton SRW Ram trucks are nearly the same (with minor variances) proving the drivetrain and frame have the same strength and capability; otherwise, they would be rated differently.
So . . . the ONLY reason the "on-the-record", legal payload rating for the 3/4-ton trucks are so low is because the empty weight of a truck MUST be subtracted from the GVWR to determine the legal payload rating. Since the GVWR is "artificially" low to meet the 10,000 lb. and under GVWR licensing and registration requirements, it goes without saying the payload rating is also "artificially" low. For those who purchase a 3/4-ton truck this is a classic case of getting more than you bargained or paid for!
