2024 F-350 Pro-Trailer Set Up Question 5th Wheel to Gooseneck

[M and E]

On my 2025 340RL, I replaced the original pin box with a Gen-Y gooseneck.

When you’re setting up your trailer in the truck’s system, would you select “fifth wheel” or “gooseneck” in this situation?

I’m not sure whether we’re supposed to go by the current connection type or the trailer’s original design. I can experiment with it, but I’m curious if anyone knows the correct approach for sure. I've emailed Ford too but seeing if anyone has already done that. It is not clear to me in the owner's manual.

I have a Ram so not particularly helpful to you but...
When it asks me the trailer type two options are available — Conventional or Gooseneck/Fifth Wheel.
I can't imagine a functional difference in gooseneck or fifth wheel to a tow vehicle.

I am entirely new to the gooseneck connection. However, I did a bunch of research before switching. One of the reported functional differences between a goose and fifth wheel connection is the trailer response to driver inputs; traditional fifth wheel kingpins are slower to respond and typically have lag before steering inputs influence the trailer (forgiving) whereas a goose has almost none to zero lag (unforgiving) before the trailer reacts. I've only backed it 8-10 times so far but the near-zero lag and the trailer responding more sharply to steering inputs is proving to be accurate. The Fords use a yaw sensor that informs the backing/steering software. Unsure if the Ram has that same tech.
