Congrats on the new truck Steve! To add a gooseneck hitch to your 2025 GMC Sierra 2500, I recommend the Curt item # C60642. This gooseneck hitch is the same one GM installs in their brand new trucks. The custom fit brackets install into preexisting holes in your Sierra's frame.
I have attached a couple of pictures below along with an installation video to help you get this hitch set up and show you what it looks like once installed.
To make towing with a gooseneck trailer easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 7' Long item # C53CR. This harness puts a 4-way and 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your gooseneck trailer easier and more convenient.

Hey Steve, how did the Curt gooseneck hitch work out on your Sierra 2500? Did the custom brackets line up well with the factory holes in the frame? Your update could make it easier for others adding a hitch to the same truck.
