Hello Patrick,

I am really glad you wrote in before ordering because the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box for Lippert 1621/1621HD # GY38FR is not the correct fit for your trailer.

Thank you for including the photo. I was able to send it to Lippert and confirm that your trailer is equipped with a Lippert Rhino pin box. For your setup, you will need the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box for Lippert Rhino # GY33GR.

You will also need the Safety Chain with 2 Hooks for Gen-Y 5th Wheel to Gooseneck Pin Box # GY49GR, as safety chains are required when using a gooseneck connection.

Making the switch to a gooseneck setup is nice because it frees up the truck bed and eliminates the need for a bulky 5th wheel hitch.

Do you already have a gooseneck ball installed in your truck? If not, let me know the year, make, and model of your truck, along with whether it has the OEM prep package, and I'd be happy to recommend the correct setup.

Any big summer trips planned, which one are you looking most forward to?
