Dump fuel for max tow?

200 lbs is nothing for limited use. I wouldn't want to drive any truck loaded right up to the max allowable on a consistent basis. Even being over by a few hundred pounds isn't going to cause catastrophic failure or create a safety issue. That would only be 5-10% over depending on the truck. But driving consistently at even 80-90% of your limit will lead to premature wear.
IMO, that doesn't seem like a significant deviation; whether you're at 100% of GVWR or at 103% of it, you're still going to need to adjust your driving accordingly (especially if you've concurrently gone from 35% to 75% of GCWR). I wouldn't want to make a habit of it, but on an occasional basis, I'd be comfortable at 103% of GVWR in a well-maintained F-150.

200 / 7050 = 2.8%.

Assume a payload capacity of, say, 1,700 lbs, then the OP would be close to 12% over. That's not insignificant.

Except that 'payload' is a meaningless number, the goal is to not be over GVWR which is +/- 7000lb (depending on your model/engine/drivetrain/etc). So you're 12% over a meaningless number but 3% over the number that means something.

How do you determine if you are under payload or not? That's nearly impossible to do accurately. You would have to have 1st weighed the truck bone stock with a full tank of fuel and no occupants to verify the sticker is correct. Then you would have to weigh everything you put in the truck, mods you put on the truck, subtract anything you take out of the truck, and weigh tongue weight of a trailer....If you load the truck down then weigh it, then you are actually striving to stay within the GVWR, not the payload capacity.

I'm fairly certain, in a court of law, you are good with what is stated on the mfg's certification stickers, as the law is why they are there.

You also would be adding weight in and above the bed, while the tank resides below the bed, so you are also changing the center of gravity.
If you are going to hit the highway at 75mph, all other drivers be damned, I'd say no to this proposition. However, if you are going to take it easy, give extra room between you and the vehicle ahead, take more time to make lane changes and navigate corners, I'd say you will be no worse for wear, except for the extra wear of being at max payload.
If the two trailers stacked raises them well above the roof line, take into account the higher center of gravity. I've seen two trucks with rooftop tents in which the drivers failed to take into account the change in handling a high center of gravity can inflict upon even a large truck. I can't even imaging having to explain that my truck ate it because of a damn tent.
