I have a curt double lock gooseneck hitch in my 2004 f350. Can I install this around that gooseneck or Will I need to remove it? Or is there other options? Thanks

Hi Ethan; you won't be able to install base rails with the Curt Double Lock already in your 2004 F-350 unless you want to remove the gooseneck hitch. What you can do instead is use an adapter. Assuming this is the regular Double Lock you need the Curt X5 5th Wheel Base Rails Adapter for Curt Double Lock Gooseneck Trailer Hitches # C16210. If you have the EZr Double you need the # C16220 instead.
