Expert Reply:
Have you tested the center pin of the 7-Way on your 2023 Chevy Silverado 3500 with a circuit tester like part # PK12741, or have you just been testing that circuit with your boat trailer? If you've been testing it with just your boat trailer then try testing your vehicle and the trailer apart from each other. You can use a different truck with your trailer and a different trailer with your truck to accomplish this.
If you have tested your reverse pin with a circuit tester and your fuse for that function looks good then I'd honestly take your truck to a GM dealer as there is either an issue with the OEM wiring or something going on with the computer.
Hope this helps point you in the right direction!
