I am about to go look at a 2018 F350 with 6.7 Turbo diesel. Based on a gear ratio of 4.1 (the listing is wrong, I had the dealer verify on the white sticker in the door) I am expecting a 5th wheel weight of around 30k and towing of around 20k. Does that seem right?
You will find the payload on a yellow sticker in the drivers door. See below, mine is 1760, yours will be much much more. Do NOT listen to the dealer salesperson for technical advise, there are very few in sales that know what they are talking about, they quote brochure numbers, not your actual truck numbers. Then you have to find out what the pin weight of the 5r you are looking at. Make sure it is a loaded gross weight. Do not assume anything, do your homework, many many people buy things that do not work.

Whether it's your F-150 or an F-350 you want to buy, the same variables come into account. The 5th wheel will sit above the rear axle. It will impact PAYLOAD, so you have to know the truck's payload, and subtract the 860 pounds of people you have. Then, assuming that the pin weight doesn't exceed the remaining payload, you also need to see if that weight exceeds the axle capacity. Remember of course the mounting in the bed that the pin attaches to also comes off the payload.
And, as noted already, the factory weights are IRRELEVANT. You need to use the maximum weight that the trailer will be, i.e. GVWR, because when you load it up it will put more weight on the pin. While a regular trailer may gain 1,000 - 1,500 pounds loaded with your stuff, you'll want to research carefully what a 5th wheel gains.
As stated, neither the dealership salespeople nor the trailer salespeople should be relied on for this information. You need to gain a complete understanding and make sure you know you're within limits.
based on the link you provided:
see page 26 of the towing guide
If a 4.10 gear ratio on a 4x4 with 176" wheel base GCWR is 40,000 Tow rating is 21,000 Goose neck rating of 31,600(2)
NOTE (2) Gooseneck tow rating shown. 5th-wheel tow rating limited to 5th-wheel hitch rating of 27,500 lbs. (This is due to the rating on the Ford OEM Fifth wheel hitch for that year.
It depends on the wheel base, drive train and gear ratio and of course all of the warnings regarding Payload and GVWR apply. It's much easier to figure this stuff out with the super duties especially the DRW models.
depending on state exceeding certain Gross Combined Weight Ratings and/or length requires special licensing (Non-Commercial Class A for example or in some case actual CDL). Check your State licensing and registration requirements.
Not to add insult to injury.....the Diesel trucks often have a sacrifice in payload to allow for the more heavy motor.
You are still sort of confused on trailer towing.
It is never about how much weight you can pull behind you. It is ALWAYS, how much weight the truck can support. In your other threads, your truck can support 1900 lbs, which is quite a lot for a 1/2 ton truck.
An F350 can tow a house by horsepower number, however the truck cannot support a house.
I'm not sure this is even a valid thread. Sorry, just guessing but at first you're trying to figure out how to connect a moderate trailer to your F150 then you all of a sudden jump to a 1-ton and a 30,000lb 5th wheel overnight?
There is a stark contrast between your two asks.
Regardless of you swapping the base model non tow equipped 1/2 ton or a dually F-450 -there is still a payload you have to consider. None of which can actually be started until you physically see the payload for a particular truck. Chances are Platinum F-450 will max out of payload before it meets the maximum combined vehicle weight. Again, because combined weights are typically a pipe dream because we like nice vehicle that reduce payload and prevent us from connecting or pipedream trailer.
