Sure thing, we can get your 2021 Chevy Silverado 2500 set up with 5th wheel base rails as well as a 5th wheel wiring harness so you can use your Valley 5th wheel hitch. Let's go ahead and start with the base rails for your truck, and the ones I highly recommend are from Curt:

- Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck # C16429-204

The reason I really like this install kit is because it does not require any drilling into your Chevy's frame rails to install. Not having to drill into your rails is not only great for your truck but will benefit you whether you are doing the install yourself (saving hours) or having a professional do it (less install time = less expensive labor costs). These are industry-standard base rails so they are going to be compatible with your Valley 5th wheel hitch as well.

Then the other thing you will need is a 5th wheel wiring harness, and I also like the option from Curt:

- Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector and Cover Plate # C53CR

This harness is a custom fit for your 2021 Silverado 2500 and one really cool thing about it is the cover plate it comes with, which is designed to fit right in the factory socket of your truck to give a really clean look.
