5th wheel and goose neck puts weight on the whole truck.

Identical in what way? The heavy service front springs are 1 up from whatever the truck would otherwise come with. So a truck that would come standard with 5200 springs would get 5600 springs with the HSFS. Snow plow bumps up the spring rate even higher, that same truck would get 5990 springs with the snow plow prep.

And you have a gas motor, low option, super cab.
I am pretty sure the OP is in a crew cab diesel lariat 4x4 to pull his 16k trailer. Pretty typical but is welcome to chime in more detail.
And since I have had that same truck and would gooseneck at 15k regularly I would suggest the heavy service front springs. Will give a margin of safety and not bottom out.

Well there you go...exactly what I was looking for even with a poorly worded question provided
Good to know the sp springs will bear more weight, my shop 350 w/hsfs struggles sometimes when the roof racks really get loaded up

Bottom out? Is that a thing with diesels? I had my front suspension loaded to within a couple hundred lbs of its rated max and never did it bottom out and that plow hanging out 3-4 feet in front of the truck sure try's. I can't imagine a truck with even more margin and the weight mostly in the rear ever having a bottoming out problem. I guess everybody worries about different things. This though, doesn't really seem like a real problem.

About 1" front height is added. It's a bit stiffer when empty. I drove two back to back and there is a difference in stiffness but not a huge difference IMO. I have read the difference feels much greater on gas engine trucks b/c the engine is lighter but I have (and test drove) diesel so no personal experience.
Front end wander is worse b/c there is less caster. Adding caster shims makes a huge improvement, at least it did for me.

Front end wander? Disagree.
Its a very slight spring difference on a 350.
I don’t think I’ve driven a more stable, sure footed vehicle on and kind of surface, empty or towing heavy. No sag, no sway and very sure footed and road gripping around any corner.
We’re you driving an F-450 wide track? There is a natural wander due to the wide track tracking out of normal tire paths.
