Hello Scott,

Thanks so much for writing in, and a big thank you for including the information on your current pin box. That definitely helped!

I was able to reach out to Curt to confirm the pin box number. Your current one is a Lippert Rhino. For your setup, you’ll want the Shocker 5th Wheel to Gooseneck Pinbox for Lippert 1621/0719 and Rhino Box - 24K GTW - 6K TW # SHK23MR.

You’ll also need the Safety Chain Kit for Shocker Hitch 5th Wheel to Gooseneck QuickAir Hitch - 42" Long - 24K lbs # SHK35MR.

Once you get the new Shocker hitch installed, where are you headed for your first trip to test out the new setup?

Thank you. I wasn’t sure which one I needed for the Lippert pin box. We are heading to The playful goose campground in Horicon Wisconsin for Memorial Day weekend. But do have a closer trip planned on Mother’s Day weekend in Fremont Wisconsin. We try to go every other weekend

@ScottU I just looked up the Playful Goose campground, looks like a nice relaxing spot! I try to get out on the water fishing about the same as your camping. Have to make sure you balance your work life with some play. - Safe Travels =)
