Question:

I need an adapter that will let me add a set of base rails to the bed of my truck. I have a Curt A16 5th wheel hitch and the 2016 Chevy Silverado I bought has the B&W Turnoverball system with the square gooseneck receiver. Is there a way to mount the A16 with the B&W?

Congrats on the new truck! To use your Curt A16 5th Wheel Hitch item # C16521 with a B&W Turnover Ball System you will need the Demco 5th Wheel Base Rails Adapter item # DM6140. This adapter will drop down into the square receiver and provide you with a set of industry standard rails.

This adapter is made in the USA and has a 21,000 lbs capacity. If you have a bed liner you may need to cut into it depending on the thickness to get the adapter to sit all the way inside the receiver.

I have linked a review video and a picture below to show you what this adapter will look like installed.

To make towing with a 5th wheel easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 10' Long 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.
