How to Tow a 5th Wheel Trailer with a 2017 GMC Sierra 2500 Curt Gooseneck Hitch Installed  


I have a 2017 GMC 2500 and It currently has a Curt gooseneck package installed on it. Will the frame to rail supports still fit considering there is the Curt gooseneck hitch already installed and the hitch rail brackets attach to the frame? 16516,C16411-204


Expert Reply:

The Curt Custom Fifth Wheel Installation Kit # C16411-204 is designed for your 2017 GMC Sierra 2500 but it won't fit if you already have a gooseneck hitch installed. With this being the case you still have a few options; you can use a gooseneck to 5th wheel adapter, an adapter rail kit, or remove the gooseneck altogether and replace it with the Curt installation kit mentioned above. Here is what you'll need depending on the situation:

Gooseneck to 5th Wheel Adapter
Convert-A-Ball Cushioned Adapter w/ Offset - # CAB-C5GX1216

Adapter Rail Kit
Curt X5 - # C16210 (if you have Curt Double Lock # C607-604)
Curt X5 - # C16220 (if you have the Curt EZr Double Lock # C611-624)
No Adapter Rails for Curt Overbed Gooseneck Hitch - # C61301-52
