Hi Patrick!
While we definitely have an option for your 2018 Chevy Silverado 3500 dually, the # C60730 is specifically for a Ram and is not the one you are going to want. With that said, you will want the following part:
Curt Double Lock, Flip and Store Underbed Gooseneck Hitch w/ Installation Kit - 30,000 lbs # C607-604
This will fit you truck whether you have the 6-1/2 foot or 8 foot bed and we even have an install video of it being installed on a 2018 Silverado 3500 dually, which I also included.
One other thing you might be interested in, if you don't already have it, is in-bed wiring. The Pollak Gooseneck T-Connector with 7-Pole # PK11893-11932 installs in your bed so you don't have to drape your wiring over the tailgate to get access to the 7-way on the bumper. It isn't 100% necessary, but it does make things a little easier.
What kind of trailer will you be towing?
