Question:
My 2013 Sierra Denali HD already has a Curt EZr Gooseneck installed under the bed, will this Underbed Kit still fit

In order to install a different 5th wheel or gooseneck installation kit in your 2013 GMC Sierra the old one, C611-605, would have to be completely removed.
The alternative is to keep the gooseneck hitch you have and use the X5 adapter, # C16220, and a hitch that fits in above the bed 5th wheel rails such as the Curt Q24, # C16546. I have linked a video review of this hitch for you.
