INSTALLING A B AND W GOOSENECK HITCH IN A 2020 GMC SEIRRA 2500

Question:

Where should the hole be drilled for a B and W gooseneck hitch in the bed of a 2020 GMC 2500 with a 6’ 10” long bed?

Great question! The 4" hole should be drilled 37-1/8" from the back edge of the bed and not the tailgate. If you have a spray in bed liner add 1/16 to 1/8". If you have a drop in bed liner, remove the bed liner and it can be reinstalled later.

I have included a link to help walk you through the instillation of the B and W gooseneck hitch.

I also recommend 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole Plug - GM, Ford, Ram, Toyota - 9' Long Item # 50-97-410

I have included a video link of me installing the wiring on a 2018 GMC Sierra 2500 to help walk you through the instillation. The instillation will be the same for your 2020.
