You are in luck Jody! There is an aftermarket underbed puck system that fits the 2012 Chevy Silverado 3500. It is the Elite Series Under-Bed Gooseneck Complete Hitch item # RP30158-68. This is the same puck system that Ford installs in their trucks from the factory so it's going to work with your Demco 21K without needing an adapter or a conversion kit.
I have linked a couple of installation videos below so you can see how to get this puck system installed.
To make towing with a 5th wheel easier, I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C56000. This harness puts a 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 5th wheel trailer easier and more convenient.

Hey Jody, how did the Elite Series under-bed puck system work out with your Demco 21K hitch on the Chevy 3500? It sounds like a solid match without needing a conversion kit. Sharing how it went could help others looking to reuse their hitch setups too.
