All I am saying is use common sense and don't take the GVWR number as the exact number.

Please stop spreading this nonsense. It's an old scared man's tale and has no place here. The trucks and trailers are rated to tow at max GCWR, GVWR, and GAWR. And they do. Just fine. Up and down the tallest passes in the country. Ive done it. There are legions of engineers in the auto industry that design and test this stuff to perform and your just insulting them.
The the OP: my gut reaction is no, you don't have the available capacity for such a big tank, and that's what you get for sticking with a SRW.
While the dry tongue weight of that trailer is quite low considering it's size, with it's large CCC and 15,700 GVWR rating, your going to be at over 3k lbs on the bed, when loaded. It tells me (without seeing it) it has a large inviting basement and big tanks.
Depending on how you've optioned your truck, your going to be close on rated payload as it is. Remember the fancy platinum trucks have less payload then a XL.
Really you'll be over the truck GVWR anyway, so let's talk RAWR. A 2003-2016 F-350 has a 7000lb axle, a
2017 has a 7200b axle. You didn't tell us which.
We have a very similar setup to you, and last CAT scale I was at 6800lbs RAW on my 17. So I had 400lbs to spare, but that's still not enough for your desired 75 gallon tank. I'm guessing 50lbs for the tank and 450lbs for the fuel. 500lbs total.
In the end - its going to depend on how you load the trailer, what hitch you have, and if you intend to have rear passengers. You need to load it all up, just like your going camping, this includes passengers and cargo, and go to a CAT scale and look at it. The scale will tell you what you can do.
Again my guess is no.
Now all is not lost We are considering a Titan midship, which adds about 21 gallons, mostly under the driver (and on the front axle), to help alleviate our small tank. We had one on the last truck and it made a huge difference. Doesn't take any bed room either.
